High-strength hydraulic support production welding new method

Abstract

A high-strength hydraulic support production welding new method includes the following steps: a first step, performing rust cleaning and grinding treatment on a steel plate, and cutting the steel plate according to a given size; a second step, selecting an adaptive high-strength welding wire; a third step: firstly welding inner main ribs and inner rib plates and secondly welding outer main ribs and outer rib plates while welding different types of top beams according to a welding sequence, firstly performing whole backing welding, and then performing filling cover surface welding; symmetrically performing welding from the center of a welding joint to two sides; and firstly welding vertical weld joints, and then welding horizontal joints; a fourth step, timely clearing a welding bead, and welding the next layer while the temperature drops to 50 DEG C, wherein two butt-joint welding joints should be symmetrical to each other, connection parts of joints must be staggered during multi-passwelding. The advantages of the invention are that the high-strength hydraulic support production welding new method is simple and skillful in principle, is simple in operation flow, is wide in application range, can strictly control the cutting size, can ensure non-clearance welding, can reduce material waste, can reduce deformation after welding, can ensure the product quality, can prolong the service life of the products, and can reduce the production cost.

Description

technical field [0001] The invention belongs to the field of welding technology, and in particular provides a new production welding method for a high-loud hydraulic support. Background technique [0002] With the continuous promotion and wide application of hydraulic supports, the demand for hydraulic supports has become larger. To open up the market and improve competitiveness, it is necessary to consider reducing the manufacturing cost of products in order to win in market competition. In the hydraulic support manufacturing industry, welding is completed Finally, annealing treatment must be carried out to eliminate welding residual stress, improve the plasticity of the weld, and improve the comprehensive mechanical properties of the weld, which increases the cost of the product and the production cycle. Contents of the invention [0003] The object of the present invention is to solve the above-mentioned existing problems, especially to provide a new method for producin...
