Welding Arc Stability
AC Welding: The stability of AC arc is relatively poor. The direction of the alternating current changes periodically, and the arc will extinguish and re-ignite when th...
The thermal conductivity of copper and copper alloys is more than 5 times that of carbon steel. Welding is prone to pores, lack of fusion, and thermal cracks. The selection of welding wire direc...
Single-sided welding with double-sided formation is a core technique that welders must master, and it is particularly critical in the welding of pressure vessels and pipelines. It requires the wel...
The welding parameters of electrode arc welding mainly include electrode diameter, welding current, arc voltage, number of welding layers, power source type and polarity, etc.
1. Selection of elect...
One of the most frustrating moments for a beginner welder is striking an arc only to have the electrode stick to the workpiece. It sticks, glows red, and you scramble to twist it free. Don’t worry...
1. Reduce stress concentration The stress concentration point of the fatigue crack source on the welded joint and structure, and all means of eliminating or reducing stress concentration can improv...
