The butt joint clearance is uniform, but the numerical value is too large, so that the welding seam is easy to be penetrated and penetrated, the welding seam is poor, and the service life of a finished product of the movable arm is influenced; the butt joint clearance is uniform, but the numerical value is too small, the welding line and the base plate are not fused, the welding line detection penetration is not enough, and the strength of a finished product of the movable arm is influenced; the butt joint clearance is not uniform, the appearance of the welding seam is poor, and the size of the welding leg does not meet the requirement. The movable arm assembling clearance is not well controlled, and the integral use performance of the product is easily influenced.
In view of the structural characteristics of the boom, the steel plate butt joint gap needs to be controlled. At present, the following aspects exist in controlling the butt joint gap of steel plates: 1. the measurement is performed manually with a measuring tool such as a steel plate ruler.
