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.

When operating a medium-frequency inverter spot welding machine, the following key points should be noted: 1. Safe operation; 2. Equipment inspection; 3. Correct setting of welding parameters; 4. Cleaning the work surface; 5. Controlling electrode pressure, etc.

The electrodes of a medium-frequency inverter spot welding machine are the components that directly contact the workpiece during the welding process. Therefore, their material needs to meet a series of requirements to ensure good welding quality and durability.
