威廉希尔官方下载Stainless steel is a very common type in our daily life. With the continuous expansion of the stainless steel market in our country, the consumption of stainless steel plates has also increased year by year, and thin-walled stainless steel plates have also penetrated into various production and manufacturing fields. Welding has become an important process in manufacturing. However, the welding process characteristics of thin-walled stainless steel plates determine the difficulty of welding.
The most difficult problem to control for thin stainless steel welding machines is welding penetration and deformation: stainless steel sheets are less constrained and are subject to local heating and cooling during the welding process, resulting in uneven heating and cooling, and uneven welding Stress and strain, when the longitudinal shortening of the weld seams the pressure on the edge of the thin plate exceeds a certain value, a severe wave-like deformation will occur, affecting the appearance quality of the workpiece.
威廉希尔官方下载In general, the main ways to solve the burning through and deformation of the stainless steel sheet when welding are:
威廉希尔官方下载(1) Strictly control the heat input on the welded joints, and select the appropriate welding method and process parameters (mainly welding current, arc voltage, welding speed);
(2) Strive for accurate assembly dimensions and minimize the interface clearance. The gap is slightly larger and it is easy to burn through or form a large welding knob;
(3) Hardcover clamps must be used, and the clamping force is evenly balanced. The key to welding stainless steel sheet is to pay attention to: strictly control the line energy on the welding joint, and strive to minimize the heat input under the premise that welding can be completed, so as to reduce the heat affected zone and avoid the above-mentioned defects.
Deformation of stainless steel sheet by argon arc welding is unavoidable. It can only be used by step backward welding method. The current used should not be too large, and the heating time of the plate should be shortened as much as possible, so as to minimize the deformation of the plate.
威廉希尔官方下载The best stainless steel sheet is laser welding of 0.1MM. The laser spot size can be adjusted arbitrarily, which can be well controlled. The deformation ratio is also absent.
The laser welding machine is undoubtedly the best choice for solving stainless steel sheet welding!
