the method comprises the following steps that firstly, according to the butt joint angle of a welded metal piece, a worm (43) is driven to rotate clockwise or anticlockwise through a first knob (44), a worm wheel (46) is prompted to drive a swing rod (47) to swing anticlockwise or clockwise until the angle formed by a supporting rod (42) and the swing rod (47) meets the butt joint requirement, a knob positioning nut (45) is in contact with the bottom of a shell (41), the worm (43) is braked, and the butt joint angle adjustment is completed;
secondly, the two metal parts are respectively placed on the clamping mechanisms (5) on the left side and the right side, the two metal parts are contacted by the welding ends, the second knob (57) is screwed clockwise, and under the limiting effect of the sliding block (54) on the second clamping plate (55), the screw thread rotating force of the screw rod (56) is promoted to drive the second clamping plate (55) to move downwards until the second clamping plate (55) and the first clamping plate (53) clamp and fix the metal parts, so that the butt joint of the two welded metal parts is completed;
and step three, the placing angle of the protection mechanism (6) is adjusted by adjusting the first angle adjusting seat (1) and the second angle adjusting seat (3), the telescopic rod (2) can enable the protection mechanism (6) to rise or fall, the protection mechanism (6) is located at a position convenient for protecting eyes of an electric welder, the electric welder can clearly see welding points through the glass plate (63), when the eyes are protected, the forehead of the electric welder extrudes the pressing plate (649) to enable the pull rod (648) to push the push-pull plate (646) to move backwards, the connecting rod (647) further pushes the two moving blocks (644) to move inwards and extrudes the spring (643) until the two goggles (645) are contacted with each other, the goggles (645) shield eyes of the electric welder to prevent the eyes from being punctured by light rays during welding, therefore, the eyes can be protected without holding the mask by hands, the actions of lifting and lowering the mask repeatedly are reduced, and the welding efficiency is high.
