Why do certain materials need to be preheated before welding?

In order to slow down the cooling rate of welded parts and prevent the occurrence of cold cracks.

Why do some welded components require post weld heat treatment?

In order to eliminate welding residual stress and improve the microstructure and properties of welded joints.

Why is it necessary to develop a welding process specification before welding?

Ensuring welding quality relies on five major control links: human, machine, material, method, and environment. Human - Welder's operational skills and experience - Machine - High performance and stability of welding equipment - High quality method of welding materials - Correct welding process regulations and standardized operating environment - Good welding operation environment. Before welding, welding process regulations formulated based on welding tests and welding process evaluation are "regulations" and important factors to ensure welding quality.

Why is it necessary to treat the surface of the base metal before welding?

If there are impurities such as oil (paint), water, rust, etc. on the groove and surface of the welded joint, they will melt into the weld seam and produce defects such as pores, inclusions, slag inclusions, cracks, etc., which will bring harm and hidden dangers to the welded joint.

What is the melting coefficient of welding wire?

The melting coefficient of welding wire refers to the amount of welding wire melted per unit of time when passing through a unit of current. The finer the welding wire, the higher its melting coefficient and efficiency.
