Recently, PDKJ successfully delivered a "filter end cap projection welding machine" to customers in the Malaysian automotive manufacturing industry. With its excellent automation performance and high efficiency, the equipment helped customers achieve automated spot welding of filter end caps, significantly improving welding quality and production efficiency.

Optimizing Laser Power and Pulse Frequency Matching for Rocker Arm Laser Spot Welding of 2mm Stainless SteelWhen performing rocker arm laser spot welding on 2mm-thick stainless steel, the core goal of optimizing the matching between laser power and pulse frequency is to achieve sufficient penetratio

Recently,PDKJ drew on its deep know-how of automotive manufacturing to engineer a tailor-made seam-welding machine for an automaker in Xi’an. From initial briefing through design to final shipment, the entire process took only 50 days, successfully eliminating the twin pain points of speed and quality in high-strength-steel crash-beam welding.

Recently, Guangdong PDKJ Automation Technology Co., Ltd. successfully delivered a tailor-made “automatic cutting & welding machine for radiator tubing” to a machinery-equipment customer in Guangdong. The on-time completion of this project has injected fresh momentum into the client’s production line and once again demonstrates PDKJ’s formidable strength in welding automation.

Different industries have vastly different preferences for welding equipment due to their unique production needs and product characteristics. The automotive manufacturing industry focuses on efficient, precise, and high-strength welding, with laser welding and robotic laser welding machines becoming the key to enhancing competitiveness; The electronic and electrical industry pursues precise, minimal, and low heat affected welding results, and laser welding machines stand out with their excellent precision and stability; The aerospace industry has strict requirements for high-performance, high reliability, and complex structure welding, which has made laser welding machines and electron beam welding machines shine brightly; Under the comprehensive consideration of high sealing, high precision, and large-scale production, laser welding machines are the preferred choice in the new energy industry.

In large-scale spot welding scenarios, spot welding machines occupy high efficiency with their efficient spot welding capabilities and low-cost advantages; Laser welding machines have demonstrated excellent welding efficiency in the fields of precision and thin plate welding with their high precision and speed characteristics; Robot laser welding machines, with their intelligent automation and flexible motion capabilities, have become a leader in improving welding efficiency in complex workpieces and large-scale automated production. Enterprises should choose welding equipment reasonably based on their own production needs, product characteristics, and financial and technological strength, in order to maximize welding efficiency and economic benefits.

In the scorching summer of August, the warmth is strong. On the morning of August 18, 2025, the PDKJ administrative department's carefully prepared August employee birthday party was warmly opened in the company's conference room. All employees in the factory gathered together to send their sincerest wishes to the three birthday stars, allowing the corporate mission of "pursuing material and spiritual happiness for all employees" to take root in the details.

In the vast world of manufacturing, welding technology is like a solid bond, cleverly connecting various metal materials to build the infrastructure of countless products. Spot welding machines, laser welding machines, and robotic laser welding machines are the "main forces" in the welding field, each with their own unique skills. However, how to accurately select the most suitable equipment based on specific production needs has become a key decision faced by many enterprises. This not only concerns current production efficiency and product quality, but also has profound implications for long-term cost control and enterprise development.

From the perspective of automation processes, robot laser welding machines can be regarded as a highly intelligent model. In the initial workpiece positioning and clamping process, it utilizes high-precision robotic arms and advanced visual recognition systems to accurately grasp and fix the workpiece, ensuring precise welding position. Taking automotive parts manufacturing as an example, robotic arms can quickly identify target components in complex workpiece stacks and accurately place them on welding workbenches without manual intervention. The positioning accuracy can reach ± 0.05 millimeters, far exceeding manual operation accuracy.

Spatter is a common yet critical issue in laser welding. Defined as the ejection of molten metal droplets from the weld pool, spatter not only mars surface appearance but can also adhere to optical components, increasing maintenance costs and even causing permanent damage. To eliminate or minimize spatter, a systematic approach covering parameters, process, material preparation, and shielding gas is required.

In modern manufacturing, laser welding machines—thanks to their unique advantages—are now used across a wide range of industries. One of the most critical performance indicators is the span of material thickness they can weld. Laser welders can join materials from ultra-thin foils to comparatively t

As a key equipment for achieving efficient connections in metal processing, the welding quality of spot welding machines directly affects the structural strength and service life of products.

In the field of metalworking, spot welding machines are commonly used welding equipment. They generate heat through electric current to bring the contact points of the workpieces to their melting point, fusing them together to achieve the weld.

The intermediate frequency inverter spot welding machine may encounter some minor malfunctions during use. Resolving these faults typically requires inspection and maintenance of the equipment. Here are some common minor faults and their solutions:1. Unstable welding or poor welding qualityReason: e

The workflow of an intermediate frequency inverter spot welding machine usually includes the following basic steps:1. Preparation work:Before spot welding, it is necessary to prepare the welding equipment and workpiece, including checking the equipment status, confirming welding parameters, cleaning

In industrial welding, a single machine seldom covers every requirement; combining spot welders with laser welding systems leverages the strengths of both technologies, delivering an efficient solution for complex workpieces.Spot welders excel at fast, high-strength point connections, making them id

High-strength steels, prized for superior tensile strength and fatigue resistance, are widely used in heavy-load sectors such as construction machinery, bridges, and pressure vessels. Yet their weldability is far more demanding than that of ordinary steels; only through scientific equipment selectio
