How to weld stainless steel sheets?
At present, there is no good solution for the welding of thin plates in the stainless steel product industry. Many thin plates (0.2mm) will have deformation and undercut problems after argon arc welding. This is caused by argon arc welding. The high temperature is caused by too much impact on the base material. Is there no good solution for thin plate welding?
Specific analysis of specific issues, not afraid of difficulties, but afraid of not having a heart to study! Through analysis and verification, we can choose the most suitable welding machine from a variety of welding machines on the market. Let me lead you to do some specific analysis!
There are many types of welding machines on the market, and we can select a few of the most commonly used machines for comparison. Selection object: gas shielded welding, argon arc welding, electric welding, cold welding.
Gas Shielded Welding
Gas shielded welding plates generally require a relatively high plate thickness. If gas shielded welding is used for welding under 1.5mm, it is easy to deform and burn through the plate. So gas shielded welding is unnecessary!
Argon Arc Welding
When the thickness of the thin plate is less than 1mm, the use of argon arc welding for welding will also cause problems such as deformation, burn-through, and blackening. This is due to the high current density of argon arc welding, the concentration of heat, and the high deposition rate. In addition, argon arc welding has high technical requirements for operators, and a very experienced master can get good results when welding about 1mm, but correspondingly, his requirements for salary will also be very high. Therefore, considering, all things considered, argon arc welding is not a good choice either!
Electric Welding
Electric welding is generally used to weld steel structures. When the thickness of the welded plate is below 3mm, it cannot be welded at all. So electric welding is not advisable either!
Cold Welding Machine
There are two types of cold welding machines on the market, namely: precision repair welding machines and electric spark surfacing repair machines.
These two types of welders have different emphases. The precision repair welding machine focuses on welding and can also be repaired; the electric spark surfacing repair machine focuses on welding repair. So use a precision repair welder for comparison.
There are also many types of precision repair welding machines on the market. According to the principle of optimality, we choose the HMT-1600 precision repair welding machine. This welder has a welding effect unmatched by other similar welders on welding thin plates!
HMT-1600 precision repair welding machine, after welding, the welding scar is smooth, and there is no deformation problem in the welding seam area, but there is slight discoloration, but this can be treated with a brushed cloth. Eliminating the grinding process can also improve the working environment of the workshop. The most important thing is that this machine is small, and the whole machine is only 15Kg and easy to carry.
The machine is easy to operate and does not require professional argon arc welding welders. After about 3 hours of training, the general workers in the workshop can fully operate it. After one or two days of operation of the welding machine, the operator can weld very beautiful welds. Through the above analysis, we can conclude that the HMT-1600 precision repair welding machine adopts a small current welding method to obtain a better welding effect.
