The 2025 CMES Vietnam International Machine Tool Exhibition will grandly open at the Vietnam Exhibition Center (Hanoi) from November 12th to 15th. As the only professional machine tool exhibition in North Vietnam, this year's exhibition, with a scale of “over 100,000 square meters of exhibition area, more than 2,000 participating brands, and over 100,000 professional visitors,” has become the core platform for the aggregation of manufacturing resources in Southeast Asia.As a manufacturer specializing in the research and development and production of spot welding machines, laser welding machines, and automated welding equipment, PDKJ is fully prepared and will showcase cutting-edge welding technologies and equipment that meet market demands at booth D70. We sincerely invite industry clients to visit and communicate with us to explore new opportunities for cooperation!

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

In manufacturing welding scenarios, different products, materials, and thicknesses often require adapting to different welding processes—some need fast continuous welding, some need precise spot welding, and others require minimizing thermal deformation. This makes many enterprises wonder: as a "versatile" welding equipment, can laser welding machines switch between different welding modes? The answer is yes! High-quality laser welding machines not only support switching between multiple welding modes but also can adapt to multi-scenario production needs through flexible adjustments. Below, we will detailedly answer this question from aspects such as mode types, switching logic, and industry applications.

In manufacturing workshops, welding processes often face the challenges of "difficulty in recruiting workers, fluctuating efficiency, and high scrap rates." Many bosses are hesitant: the one-time investment in automated welding machines is not low, so how long does it actually take to recover the cost? In fact, the payback period is far shorter than imagined— the key lies in calculating the "income and expenditure account" between manual and automated welding, and selecting equipment that meets production needs. Below, we will help you figure out this account from three dimensions: cost composition, calculation logic, and practical cases.

Recently, Guangdong PDKJ Automation Technology Co., Ltd. (“PDKJ”) delivered a customized multi-head spot-welding machine for door hinges to a hardware-and-sheet-metal customer in Jiangmen. The system precisely tackles the customer’s core pain points—low welding speed, cumbersome process hand-offs and insufficient weld-spot accuracy—bringing a high-efficiency upgrade to the entire production flow.

Electrodes are an essential part of electrical circuits, and copper is one of the most widely used materials for making electrodes. Copper is a good conductor of electricity and has excellent corrosion resistance, making it an ideal material for electrodes. In this article, we will explore the prope

Copper electrodes have been used for a long time in various industries, primarily due to their excellent conductivity properties. They are essential in processes like welding, electroplating, and electrical discharge machining (EDM). This article will delve into what copper electrodes are, their pr

Too much power = wasted energy and burn-through; too little = lack of penetration and low speed. Stop guessing—just lock onto two things: work-piece thickness and material behavior. Match them exactly and you get quality, speed and low running costs. Here is the plain-English recipe.

Afraid the “high-tech” label means a steep learning curve? Don’t be. If you focus on the core sequence and follow the standard routine, an ordinary beginner can be laying down clean, basic welds on day one. Laser welders are now common in hardware, electronics, automotive-parts plants, etc. Mastering the fundamentals will multiply your productivity. The three steps below will get you started fast.

The answer is—not only can it be switched, but it can also "change the light on demand" within the same weld seam. The key factors are the laser type, control software, and interface openness. Below, we'll explain the mainstream technologies, switching methods, and key points to avoid pitfalls, so you won't be confused by the term "mode switching" when buying equipment.

Welding machines are core equipment in industrial production and maintenance. Improper storage during long-term idle periods can easily lead to problems such as aging of internal components, corrosion of metal parts, and decreased insulation performance. This not only shortens the equipment's lifespan but may also cause frequent malfunctions upon restarting, and even pose safety hazards. Mastering scientific storage methods is key to ensuring the stability of the welding machine during idle periods and extending its service life.

The core prerequisite for the collaboration of multiple welding machines is reasonable task allocation and process planning, to avoid efficiency losses caused by uneven busy and idle schedules. The use of a dynamic scheduling system is key to efficient scheduling. By establishing an order priority matrix and dividing task levels based on delivery time, profit margin, and other dimensions, a welding skill database is built to record the certification level, proficiency in processes, and equipment proficiency of each operator, achieving accurate matching of "task personnel equipment".

On the morning of 10 November, PDKJ’s conference room was buzzing with warmth as all on-site employees gathered to celebrate six coworkers whose birthdays fall this month.

Recently PDKJ supplied and commissioned a DTB-160 vertical medium-frequency inverter DC spot-welder for a Dongguan electronics processor. The machine not only cracked the tough job of welding transformer copper wire, but also seamlessly accommodates downstream products such as on-board transformers and all kinds of inductors—making it an “all-round weapon” on the customer’s line.

In industrial welding, "faster" and "flawless" are the two goals that matter. Production managers and welders often ask the same question: if we simply turn up the welding-power dial, will the travel speed rise in step-and what will that do to quality?

Small- and medium-sized manufacturers usually face a tough choice when they need to expand capacity or upgrade quality: should they stick with a basic spot-welder, jump straight to an automated laser welder, or go all-in on a robot-laser cell? The secret is to move in “gradient steps”. By matching each investment to the next clear business milestone, you can balance upfront cost and long-term return without betting the company.

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!

Recently, PDKJ’s Capacitive Energy Storage Spot (Projection) Welding Machine was successfully delivered to a leading new energy vehicle manufacturer in Hefei, providing a customized solution for its hot-formed steel nut welding production line, fundamentally solving the quality fluctuations and efficiency bottlenecks of traditional welding.

When purchasing welding equipment, many users often focus solely on the price and basic functions of the equipment, neglecting other key indicators. This may lead to the purchased equipment being unable to meet practical needs and even causing various problems during use. To avoid these pitfalls, we need to gain a deep understanding of all aspects of welding equipment to ensure that the purchased equipment can efficiently and stably complete welding tasks.

When equipment suddenly stops working, it often disrupts the normal workflow, causing unnecessary delays and losses. In such cases, it is crucial to quickly and accurately identify the cause of the fault and carry out repairs. Common causes of faults can generally be categorized into several aspects: power supply issues, electrical connection faults, mechanical component damage, and control system failures.
