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. Read More

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. Read More

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. Read More

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. Read More

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.
