For newbies in welding, faced with a array of welding machines like laser welders, handheld laser welders, spot welders, resistance welders, and industrial robots, the choice can be confusing. However, by focusing on three keys: "material, thickness, and precision," you can quickly narrow down the options.
I. Welding Material: The Guiding Factor for Welder Selection
Different materials have different welding requirements. For common carbon steel used in household metal items or general steel structures, traditional CO2 gas - shielded arc welders or resistance welders suffice due to their simplicity and affordability.
But for special materials like aluminum, stainless steel, and copper alloys, more specialized equipment is needed.Laser welders, with their high - energy - density characteristics, are great for welding stainless steel and aluminum, minimizing the heat - affected zone and preventing deformation and oxidation. For aluminum welding, argon arc welders are widely used as the inert gas protection prevents oxidation. When welding stainless steel, pulsed argon arc welders can better control heat input, reducing deformation and cracking. Identifying the welding material is crucial for selecting the right welder.
II. Material Thickness: The Determinant of Welder Power
Material thickness directly impacts welder power and type selection. For thin - plate welding (thickness below 3mm), precise energy - output devices are needed. Spot welders and handheld laser welders are ideal for their quick welding, small heat - affected areas, and minimal deformation.
For example, in making electronic - component metal housings (1 - 2mm thick), handheld laser welders can instantaneously complete welding with small, strong weld points and flexible operation in tight spaces. In high - efficiency batch - production scenarios, spot welders can rapidly form weld points through electrode pressure and electrical conduction, boosting production efficiency.
For thick - plate welding (thickness above 3mm), high - power welders like submerged arc welders or large CO2 gas - shielded arc welders are required to provide sufficient heat for proper melt depth and strength. In construction steel - structure welding (steel thickness up to 10mm or more), high - power welders must be used to ensure welding quality. Industrial robots, combined with laser or other welders, also play a vital role in thick - plate welding. They can precisely control welding trajectories, improving welding efficiency and consistency in complex structural - component welding compared to manual operation.
III. Welding Precision: The Key Measure of Welder Capability
If welding precision is not a big concern, such as in general manual welding for daily repair or simple processing, ordinary arc welders can do the job. But in precision - manufacturing fields like 3C products, medical devices, and aerospace components, where precision reaches micron levels, high - precision welders are necessary.
Laser welders, with their small focused spot size and concentrated energy, can achieve high - precision welding. For instance, in welding internal phone parts (minute in size with fine and strong weld - point requirements), laser welders can ensure part performance and reliability, unlike ordinary welders. Handheld laser welders are suitable for precision - welding scenarios requiring flexibility, allowing operators to accurately position weld points.
Robot - laser - welder - combined robot welding systems excel in high - precision welding. Robots can follow preset programs to weld complex surfaces and tight spaces, and are widely used in industries like aerospace with strict precision requirements.
