In the field of industrial welding, resistance welding and arc welding are two common welding processes. When we focus on thin plate welding, resistance welding is often more favored. Why is this?
Let's take a look at resistance welding first. Its principle is to use the resistance heat generated by the current passing through the weldment and contact to melt the metal, thereby achieving welding. The welding process is fast and can usually be completed in an instant, just like giving metal a "flash weld", where heat is concentrated at the welding site and the surrounding materials are less affected by heat. This is particularly important in thin plate welding because thin plates are delicate and cannot withstand prolonged or excessive heat, otherwise they are prone to deformation and burning through. Resistance welding can precisely control energy, just like using a delicate "thermal scissor" to apply heat precisely at the welding point, effectively protecting the shape and performance of the thin plate.
Moreover, resistance welding is relatively simple to operate, and generally does not require the addition of filler materials such as welding wire, reducing the use and cost of additional materials. The appearance of the welded joint after welding is also relatively smooth and beautiful, with fewer subsequent processing steps. For example, in automobile manufacturing, many thin plate components such as car doors and engine hoods are connected by resistance welding. The welded parts are not only sturdy and attractive, but also improve production efficiency.
Let's take another look at arc welding. It mainly relies on the arc heat generated between the welding rod or wire and the workpiece to melt the metal. Although arc welding is widely used and flexible in thick plate welding, it is somewhat inadequate in thin plate welding. Because the heat generated by arc welding is relatively dispersed and lasts for a long time, like using a "big torch" to bake thin plates, it is easy to cause local overheating of the thin plates, leading to deformation, undercutting, and even burning through, which affects the welding quality.
However, arc welding also has its advantages. It can be very useful in complex environments such as thick plate welding and field construction, but it is slightly inferior in the specific scenario of thin plate welding.
In summary, choosing resistance welding for thin plate welding is like creating a precise and efficient "exclusive welding chair" for thin plates, which can better meet the requirements of thin plates in terms of quality, efficiency, appearance, and other aspects. No wonder it has become the preferred solution for thin plate welding.
