[Butt Welding Clamps]:The butterfly welding clips can be completely fixed before butt welding,leaving only a small gap to allow the weld to penetrate completely. [Perfectly Align Panels]:These butt welding clamps can fix the metal plates or curved panel to achieve precision butt welding and edge to edge welding. [Easy to Use]:Used the welding clamp set to pinch sheet metal panels level to each other loosen the winged nut from the alignment screw then fasten two panels across from each other between the square body and the clamp block; Tighten the winged nut to ensure a secure hold; While these clamps hold panels edge to edge with a 1mm gap, you can quickly weld the sheets together. [Wide Aapplications]:These welding clamp are specifically designed for welding operations. They are ideal for welding cracked metal floors, automotive sheet metal surfaces, door skins or prefabricated panels assembled in re-peeling projects. [Material]:The welding clamp is made of chrome vanadium steel. The smooth metal surface prevents rust, is not easily deformed, and has a long service life., Manufacturer: Create idea
