Hot-rolled and normalized steel in low-alloy high-strength structural steel and alloy structural steel species with a low total content of alloying elements, and the mass fraction of carbon is generally less than 0.25%. Therefore, on the whole, the weldability is better. The general strength level i

Computer software systems in the field of welding are mainly used in the following areas: 1.1. Computer simulation techniques including simulation of the welding thermal process, welding metallurgical processes, welding stress and deformation. Welding is a complex process involving the disciplines o

This type of steel as a high-strength welded structural steel, the carbon content is limited to low, usually less than 0.18% carbon mass fraction, and in the design of the alloy composition are also considered weldability requirements, so low carbon tempered steel welding is basically similar to nor

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.

1. Welders must wear welding masks to protect their eyes when working

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
