As the most harmful type of welding defects, welding cracks seriously affect the performance and safety reliability of welded structures.-----
With the development of industry, there are many different types of metal materials that have emerged. The common ones are plated steel sheets, stainless steel sheets, aluminum alloys, copper alloys and other materials. When spot welding machine is used to weld these corresponding metal materials, d
The submerged arc welding process is ideal for important applications in pipeline, pressure vessel and tank, rail fabrication and major construction, with the simplest single wire forms, double wire construction, tandem double wire construction and multi wire construction.
There are three types of plasma arcs available depending on the power connection.(1) Non-transfer arc. The tungsten electrode is connected to the negative electrode of the power supply, and the nozzle is connected to the positive electrode of the power supply. The plasma arc is generated between the
MIG Arc Welding!MIG Arc Welding is roughly divided into two categories: MIG Inert Gas (MIG) and MIG Active Gas (MAG). There is a large selection of welders on the market that can perform both types of welding, as well as a variety of solutions for process and control options. However, the design of
The sticking electrode is the adhesion phenomenon between the electrode and the part caused by abnormal welding of the electrode and the part when the welder is spot welding.There are four main reasons for sticking electrodes in the welding process: the working surfaces of the two electrodes are not
ARC TYPES IN MIG/MAG WELDINGThere are various arc types in MIG/MAG welding. They differ in terms of the level of the amperage. In the low power range the arc is susceptible to short circuits; in the higher power range it is free of short circuits.DIP TRANSFER ARCThe arc is ignited by brief contact b
