There are various types of equipment for welding stainless steel, each suitable for different needs. Point welders, laser welders, and robot - mounted laser welders have clear advantages in specific scenarios. Combining these with traditional equipment allows for tailored choices:

When the welding quality of the core components of a product directly affects the overall performance, choosing the right reliable welding equipment can often achieve a dual breakthrough in production efficiency and product reputation.Today, we would like to share a real - life case of how PDKJ used a Desktop AC Precision Spot Welder DN - 25T to solve the welding problem of automotive connectors for an electronic and electrical enterprise in Dongguan.

In metal processing, both spot welders and laser welding machines are commonly used equipment. Many people struggle when choosing between the two: which one is more suitable for their products, PDKJ's spot welder or laser welding machine? In fact, the key lies in the material, thickness, and processing requirements of the product. Today, let's use straightforward language to explain the difference between the two and help everyone quickly choose the right device.

Welding machines are commonly used in factory workshops, repair shops, and even some household settings. Many people who first encounter welding machines wonder: Do I need special qualifications to use a welding machine? Must the operator be certified to work? Today, I'll explain these issues in plain language to help everyone understand the qualification requirements for using welding machines.

In industrial production and everyday repairs, it's common to encounter the need to join different types of metals together, such as steel and aluminum. Many people wonder: Can steel and aluminum, which are so different, be welded together? And if they can, which type of welding machine is suitable?

In today's manufacturing industry, the quality of welding technology directly affects the quality of products and production efficiency. Today, PDKJ would like to share a case of the successful delivery of the Desktop Intermediate-Frequency Inverter DC Spot Welder DB-80T to a customer in the electric heating industry in Jiangsu.

In the world of microelectronics, where precision, efficiency, and reliability are everything, the welding process plays a crucial role in defining the performance and lifespan of electronic products.

Welding has always played a critical role in modern manufacturing. From automotive components and aerospace assemblies to electronic devices and medical equipment, welding is the backbone of metal joining. Traditionally, methods like arc welding, MIG, and TIG have dominated the industry. However, th

On the morning of September 8th, the PDKJ conference room was filled with laughter and singing, and a carefully prepared employee birthday party was warmly held here. This is a collective birthday celebration held by the company for employees who celebrate their birthdays in September, which reflects the company's love and care for employees everywhere.

In the fields of mechanical manufacturing, mold processing, and engineering machinery, high-carbon steel is often used to make key components such as cutting tools, gears, and shafts due to its high strength and hardness. However, welding high-carbon steel has always been an industry challenge, as it is extremely prone to cracking after welding, which not only affects the service life of the workpiece but may also cause safety accidents. This article will analyze the core reasons for cracking in high-carbon steel welding, recommend suitable welding equipment, and provide equipment selection suggestions to help practitioners break through the technical bottlenecks in high-carbon steel welding.

Copper is widely used in the fields of electricity, electronics, and piping due to its excellent electrical conductivity and strong corrosion resistance. However, many practitioners encounter difficulties when welding copper materials. Why is copper welding so challenging? Can ordinary welding machines handle it? Is it necessary to use special processes? Today, I will explain it in plain language to help everyone choose the right equipment and processes to solve the copper welding problem.

Recently, Guangdong PDKJ Automation Technology Co., Ltd., leveraging its profound technical expertise in the welding machine field, successfully delivered the "PDKJ Medium-Frequency Extended-Arm Projection Welder" to a smart IoT customer in Hangzhou. This machine helps the customer achieve a dual improvement in production quality and efficiency in the welding process of galvanized door panels for electrical control cabinets.

Aluminum alloy is lightweight and strong, making it widely used in automotive, home appliance, and aviation parts. However, many people struggle when welding aluminum alloy: which equipment should they choose, and how can they avoid oxidation issues? Today, I’ll explain it straightforwardly to help you select the right equipment and avoid oxidation problems in aluminum alloy welding.

The instability of weld points produced by medium-frequency inverter spot welding machines may be caused by a variety of factors. Here are some possible reasons:1. Improper Welding Parameter Settings: If welding parameters (such as current, time, pressure, etc.) are not set correctly, it may lead to

In the landscape of manufacturing, welding equipment serves as a crucial connecting tool, and its performance directly affects product quality and production efficiency. When companies begin to purchase welding equipment, price is often the first factor that comes to mind. However, behind this number, there are many important parameters that determine the applicability and long-term value of the equipment. Ignoring these parameters may lead to low efficiency, unstable quality, and rising costs in subsequent use, even if low-priced equipment is purchased.

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.
