1. Technical requirements for welded structures
The technical requirements of the welded structure include material characteristics, structural characteristics, dimensions, accuracy requirements and service conditions of the welded structure.
If the welding structure material is ordinary low carbon steel, the arc welding transformer can be used; if the welding structure requirements are high and low hydrogen electrode welding is required, the DC arc welding machine should be selected.
If it is heavy welding, you can use electroslag welding machine; if it is bar butt welding, you can choose cold press welding machine and resistance butt welding machine. For active metals or alloys, heat-resistant alloys and corrosion-resistant alloys, inert gas shielded welding machine, plasma arc welding machine and electron beam welding machine can be selected according to specific conditions.
Special welding machines can be used for welding structures with fixed structure and size in large quantities.
2. actual usage
Different welding equipments can weld the same welding piece, so we should choose the more suitable welding equipment according to the actual use.
If there is no overflow power source and gas source in field welding, arc welding generators such as diesel (steam) oil DC arc welding generators can only be selected as welding equipment.
For precise weldments that are not allowed to be reprocessed or heat treated after welding, an electron beam welding machine with concentrated energy, no filler metal, less heat affected zone and high precision should be selected.
3. economic benefits
When welding, the energy consumption of welding equipment is considerable. When choosing welding equipment, the welding equipment with less power consumption and high power factor should be selected as far as possible on the premise of meeting the technological requirements.
