On October 24, 2025, the 6th Smart Manufacturing Summit for Photovoltaic, Energy Storage, Power Supply, Inductor, and Transformer (East China) will kick off at the Phase II of the Tongli Lake Resort in Suzhou! This industry event will bring together top experts, leading enterprise executives, and technical pioneers in the fields of photovoltaic, energy storage power supply, and inductor transformer, integrating industry resources in one stop to explore new directions for industry development! As one of the participating companies, PDKJ will showcase its core technologies and products in the welding equipment field, engage in in-depth exchanges and cooperation with the industry, and jointly explore development opportunities.

The CMES Huaji Exhibition | Dongguan International Machine Tool Exhibition will be held from October 29th to November 1st at the Guangdong Modern International Exhibition Center in Houjie, Dongguan. PDKJ is waiting for your visit at booth 4B42 with spot welding machines, laser welding machines, and robot welding equipment. We look forward to exploring cooperation opportunities through in-depth exchanges!

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

For companies specializing in new energy equipment and accessories, the quality of welding processes directly affects product reputation and market acceptance. A Suzhou-based new energy client, with years of experience in the energy storage and photovoltaic fields, recently introduced PDKJ’s “platform-type medium-frequency inverter spot welding machine” to address welding challenges in metal components, thereby embarking on a new phase of efficient welding.

Hardware accessories such as hinges, fasteners, and connectors, when produced in batches, have their welding efficiency directly affecting production capacity. Many manufacturers, although using spot welders, often find themselves in the dilemma of "production capacity failing to keep up with orders" due to improper model selection or lack of automation configuration. In fact, scientific model selection and automation retrofitting can significantly improve welding efficiency.

Stainless steel kitchenware, such as pots, sinks, and knives, has extremely high requirements for welding appearance, with "seamless" being the core demand. When choosing welding equipment, small and medium - sized manufacturers often hesitate between laser welders and traditional spot welders. In fact, both have their own characteristics and need to be comprehensively judged in combination with the seamless demand, production scale, and cost.

How Laser Welding WorksLaser welding utilizes concentrated heat to melt and fuse materials at the joint:Process: The laser beam delivers intense, focused energy to a small area, creating a molten pool that solidifies into a strong bondKeyhole Effect: At sufficient power levels, the beam vaporizes ma

On the morning of October 13th, the conference room of PDKJ was filled with warmth and laughter — a special October birthday celebration for PDKJ employees began in this cozy atmosphere. All the employees of the factory gathered together to extend their most sincere wishes to the four birthday celebrants. Amidst the busy production and research, they shared the happiness of the PDKJ family.

The welding of automotive parts requires extremely high precision and efficiency. For example, deviations of even 0.1 millimeter in weld points on critical components like engine mounts and transmission housings can affect performance.

Companies engaged in welding production often care about whether welding equipment can record data and whether historical welding parameters and counts can be viewed. The answer is yes. Nowadays, mainstream welding equipment basically comes with data - recording functions that can meet the needs of parameter traceability and output statistics.

The 25th China International Industrial Fair (2025CIIF Shanghai Industrial Fair) will grandly kick off on September 23-27 at the National Convention and Exhibition Center! PDKJ cordially invites manufacturing enterprises and related personnel to visit booth F066 in Hall 3 for on-site visits, detailed discussions, and cooperation!

EMO Hannover 2025, the world’s premier metalworking trade fair, will open its doors from 22 to 26 September at the Hannover Exhibition Center, Germany. We sincerely invite you to visit PDKJ at Booth 13-F21. Experience our welding machines in action, enjoy one-on-one technical consultations with the PDKJ team, and receive tailor-made solutions for any welding challenge you face. Take advantage of the show floor to meet industry peers and expand your network of partners.

During the use of laser welding machines, many companies may have the question: Can laser welding machines switch between different welding modes? For example, switching back and forth between spot welding and continuous welding. The answer is yes, most mainstream laser welding machines on the market have mode switching function, which can flexibly adapt to different welding needs. ​

Many companies, when promoting production automation, ask: Can welding machines connect to automated production lines? The answer is yes, whether it is spot welding machines, laser welding machines, or robot laser welding machines, as long as they are well adapted and designed, they can be integrated into automated production lines to achieve unmanned or less manned operations in the welding process. ​

When selecting a welding machine, the most concerned factor for manufacturing enterprises is' how much capacity can one machine meet '. In fact, there is no fixed answer to this question. The level of production capacity is influenced by multiple factors such as the type of welding machine, welding process, and workpiece condition, and needs to be combined with actual scenarios.

Recently, the domestic and international exhibition teams of PDKJ have been reporting frequent successes! At the recently concluded 25th China International Industry Fair (2025 CIIF Shanghai Industry Fair) and the EMO Hannover 2025 in Germany, the company launched a two - pronged attack and exerted efforts simultaneously, achieving fruitful results with its core technologies and high - quality products. These two exhibitions not only fully demonstrated the company's product strength and technical accumulation in the field of welding equipment, but also further expanded the global brand influence, injecting new momentum into the development of domestic and international markets.

In modern manufacturing, the strength and reliability of joints are critical to the quality and longevity of metal products. From automotive bodies to household appliances, secure connections ensure performance, safety, and durability. One technique that has become indispensable in achieving these objectives is spot welding.

Sheet metal fabrication is a cornerstone of modern manufacturing, supporting industries ranging from automotive and aerospace to electronics and construction. Among the various joining methods available, spot welding has proven to be one of the most efficient, reliable, and cost-effective techniques for assembling sheet metal components.

Spot welding machines are indispensable tools in metal fabrication, automotive production, and various industrial applications. These machines allow operators to join metal sheets quickly and efficiently by applying high electrical current through electrodes, fusing metals at precise points. However, like any industrial equipment, spot welding machines require regular maintenance to ensure optimal performance, reduce downtime, and extend their lifespan. In this guide, we’ll explore essential maintenance practices that help maximize the efficiency of your spot welding machine.

The automotive industry is one of the most demanding sectors in terms of precision, safety, and efficiency. Modern vehicles require components that are not only durable but also manufactured with the highest level of accuracy. Among the key technologies that have revolutionized automotive manufacturing, spot welding machines play a pivotal role. These machines are indispensable in assembling car bodies, frames, and other critical components, contributing to faster production, higher quality, and cost efficiency.
