Sheet Metal Welding Is The Technique Of Joining Thin Metal Sheets Together By High Temperature Or Pressure, And Is Often Used To Create Complex Metal Structures And Components. During Welding, The Workpiece Is Heated To The Melting Point To Form A Molten Pool, Which Is Solidified Into A Weld After Cooling.
Due To The Thin Thickness Of Sheet Metal, The Welding Method Needs To Consider Factors Such As Material Thickness, Welding Strength, And Appearance. Sheet Metal Welding Is Widely Used In Automotive, Aviation, Construction And Home Appliances And Other Industries. In Addition To Welding, Sheet Metal Connection Methods Include Riveting, Bonding, And Threading. Sheet Metal Welding Enables Product Engineers To Connect Individual Metal Parts To Form Complex Functional Structures.

In SUMMARY:
Stainless steel is suitable for welding with high strength and corrosion resistance requirements.
Carbon steel is suitable for high-strength and cost-sensitive structures.
Aluminum and aluminum alloys are suitable for lightweight design, but welding requires heat control.
Magnesium alloys are light and earthquake-resistant, but welding is difficult.
Copper is suitable for electrical conductivity or corrosion resistance, but thermal conductivity makes welding more difficult.
Titanium alloys are suitable for high strength, corrosion resistance and heat resistance, but welding is complex and costly.
Sheet metal due to thin thickness, welding is easy to cause deformation due to uneven heat. Common measures to prevent deformation include:
Use spot welding or block welding to control heat input.
Clamp the workpiece before and after welding.
Select the right welding process, such as laser welding or TIG welding, to reduce the heat-affected zone.
Low heat welding technology reduces the risk of local heat concentration.
Methods of inspecting weld quality include:
Visual inspection: Observe the appearance of the weld, whether there are cracks, holes or uneven weld paths.
Non-destructive testing: Use X-ray, ultrasonic or magnetic particle testing to detect internal defects in welds.
Destructive testing: Shear, tensile or bending tests are performed on welded parts to assess their strength.
After welding, the sheet metal surface may be oxidized or discolored. Processing methods include:
Mechanical sanding: Use sandpaper and polishing tools to remove discolored areas.
Chemical treatment: Use pickling or passivation treatment to remove the oxide layer, especially for stainless steel welding.
Surface coating: Improved corrosion resistance and aesthetics through coating or plating treatment.
Common welding defects include:
Welding cracks: Cracks caused by excessive cooling or stress concentration during welding.
Porosity: The gas is not discharged in time during welding, resulting in the formation of holes in the weld.
Weld edge: A defect between the weld and the base material, usually caused by improper operation.
Welding spatter: The spatter of metal particles produced during welding may affect the appearance and quality of the weld.
Welding fixture: The use of fixture to fix sheet metal in the welding process can effectively reduce welding deformation.
Reverse deformation technology: Reverse deformation is applied to the sheet metal before welding, and the shrinkage caused by heat will return to normal shape after welding is completed.
Cooling control: In the welding process, the cooling speed is properly controlled to avoid excessive thermal stress resulting in material deformation.
