To encourage the development of distributors and agents, PDKJ will offer a range of preferential policies and support measures

At the 2026 ITES Shenzhen Industrial Exhibition, Guangdong Pudian Technology made a grand appearance with a new generation of handheld air-cooled laser welding machines. As a source manufacturer of spot welding machines, laser welding machines, and automated welding equipment, we sincerely invite new and old customers to visit booth K11 in Hall 6 of the Shenzhen International Convention and Exhibition Center (Baoan) from March 31 to April 3 for tastings, negotiations, and win-win business opportunities.

On the morning of March 9, 2026, PDKJ's first quarter employee birthday party kicked off in a warm and friendly manner. All employees gathered in the conference room to send their blessings to 15 birthday celebrants born between January and March. The venue was filled with laughter and joy, demonstrating the warmth and cohesion of the PDKJ family.

For stainless steel cookware handles, strength is the baseline requirement, while appearance determines competitiveness. Choosing the right spot welding machine not only prevents issues such as weak welding, deformation, and rough weld marks, but also reduces post-processing work and rework costs—ultimately helping manufacturers improve product quality and production efficiency.

Uneven weld nuggets in spot welding can result from hardware failures, parameter misalignment, or improper operation practices. It is critical not to blame the equipment blindly. By accurately diagnosing the root cause and applying targeted corrective measures, manufacturers can quickly resolve immediate issues while establishing long-term process stability—improving weld quality and reducing rework costs.

There is no one-size-fits-all spot welding machine for welding aluminum alloys, stainless steel, and copper. The key is to select a machine that suits the characteristics of the material: stainless steel has a low barrier to entry, so cost-effectiveness is the priority; aluminum alloys require stable current for film breaking, so medium-frequency machines are the mainstream; copper relies on high current fusion, so high-power dedicated machines are crucial. Choosing the right equipment, along with suitable electrodes and welding parameters, can solve problems such as incomplete welds, burn-off, and deformation, while also improving welding efficiency, reducing rework costs, and adapting to the spot welding needs of various production scenarios.

The challenge in stainless steel kitchenware welding lies in achieving seamless aesthetics while guaranteeing structural strength. By selecting suitable welding methods, precisely controlling process parameters, properly utilizing shielding gases, and applying appropriate post-weld treatment, welding pain points can be effectively resolved. Standardized operations, equipment maintenance, and parameter documentation are key to ensuring consistent quality.

To ensure that all employees can enjoy a safe, peaceful, and joyful Spring Festival, and in consideration of the company's production and operational realities, we have decided on the following Spring Festival holiday arrangements for 2026. Please take note and make appropriate arrangements:

On January 31, 2026, Guangdong Pudian Automation Technology Co., Ltd. successfully held its 2025 Annual Summary and Commendation Ceremony & 2026 New Year Gala, centered on the core theme of "All Staff Engaged in Management, Sales Maximization, Cost Minimization."

Welding quality directly governs joint strength, safety and service life. Defective welds can cause breakage, leakage, scrap or even industrial accidents. Many companies ship faulty parts simply because they lack a standard inspection routine, which raises rework costs and damages brand reputation. In fact you don’t need complex gear to control weld quality—master four common tests (visual, penetrant, ultrasonic, destructive) and you cover the whole spectrum from quick screening to accurate verification. This article explains the operation key-points and application scope of each method; first-time inspectors and experienced QA departments can copy the workflow straight away. Core principle: follow the “shallow-to-deep, surface-to-core” logic—find obvious surface flaws first with simple means, then hunt for hidden internal defects with professional methods, and finally carry out spot destructive tests to prove overall conformity. This saves inspection cost and boosts efficiency.

Spot welders are among the most widely used joining machines in industry, yet many buyers still “step on mines” because they overlook equipment characteristics, process requirements or after-sales support. The result is higher cost, lower throughput and unstable weld quality. Below we list the four blind spots we see most often—so you can steer clear of them.

Many buyers fall into the trap of asking “Which is better, a spot welder or a laser welder?” In fact, neither is intrinsically superior; the key is to match the machine to the real production need. Choose correctly and you raise weld quality while cutting cost; choose poorly and you suffer low throughput and high rework. This article walks you through three lenses—core differences, a 4-step selection process, and real-world cases—so you can zero-in on the right welding equipment.

Different welders vary dramatically in power draw; understanding these differences and mastering energy-saving techniques is essential for cutting production costs and achieving sustainable growth. This article compares the energy use of resistance spot welders and laser welders, and offers practical tips for saving power.

Recently, PDKJ's independently developed "desktop welding machine for entire production lines" was successfully delivered to a customer in the electronic components industry. It precisely addresses the core welding requirement of forming wire terminals into a square shape, and utilizes precision and automation technologies to help the customer achieve improvements in both production quality and efficiency.

The core logic of selecting a spot welding machine is to precisely match the welder's performance with the workpiece characteristics and production pace, avoiding "overkill" that leads to wasted costs or "underperformance" that results in poor welding quality. The following provides selection solutions based on three core dimensions: material compatibility, thickness matching, and production capacity matching, combined with practical application scenarios.

Before starting the machine each day, use fine sandpaper or a dedicated electrode grinder to polish the surface of the electrode tips, removing oxide layers, metal debris, and oil stains until a clean metal surface is exposed. If the electrode tips show severe wear or deformation (such as end face indentation or increased diameter), replace them with electrode tips of the same specifications. Purpose: To prevent excessive contact resistance from causing abnormal welding sparks and unstable weld nuggets.

This article zeroes in on the real-world deployment of the PDKJ galvo laser welder at a Dongguan-based hardware-furniture manufacturer. Through a detailed case study on welding filter-housing shells, we show how the machine precisely meets the company’s stringent welding requirements, using intelligent control technology, high-speed responsiveness and rock-solid stability to solve long-standing industry pain points and deliver a proven welding solution that peers can replicate.

The quality inspection of weld spots produced by medium-frequency inverter spot welding machines typically involves the following aspects: 1. Visual inspection; 2. Metallographic examination; 3. Welding strength testing; 4. Welding performance testing, etc.

The main reasons why medium-frequency inverter spot welding machines require cooling water are for heat dissipation and maintaining the equipment's normal operating temperature. Here's a detailed explanation: 1. Heat Dissipation; 2. Equipment Protection; 3. Stable Welding Quality; 4. Improved Work Efficiency.

The quality requirements for weld spots produced by medium-frequency inverter resistance welding machines typically depend on the specific application and industry standards. However, generally, the following are some common weld spot quality requirements: 1. Weld spot appearance; 2. Welding strength; 3. Welding compactness, etc.
