Calculation and control method for welding material actual consumption

Abstract

The invention discloses a calculation and control method for the welding material actual consumption. The method includes the following steps: a, acquiring various actual welding redundancy average values of different joint types through a field measurement method; b, calculating the welding material actual consumption of each weld joint, and a calculation formula: the welding material actual consumption= the sectional area of the weld joint*the length of the weld joint* the metal density / the melting efficiency of a welding material, wherein the sectional area of the weld joint is calculated by considering the actual welding redundancy average values of the step a, and the melting efficiency of the welding material is measured through tests; and c, clearing a single weld joint and multi-weld joint, performing like term combining on all the weld joints of the whole member or unit to form welding material details, allowing the welding material details to correspond to construction units one-to-one, and performing quota budget before use and performing checking after use. The calculation and control method can remarkably reduce the welding material actual consumption and reduce the production cost of an enterprise.

Description

technical field [0001] The invention relates to a calculation and control method for the actual amount of welding materials, which can be widely used in industries such as ships and ocean engineering, steel structures, boilers, pressure vessels, etc., and is especially suitable for ships and ocean engineering with complex structures and large material usage construction field. Background technique [0002] The development of modern shipbuilding technology has gone through several stages. Since the 1950s, welding has been used instead of riveting in hull construction. The construction method has evolved from sporadic and bulk to segmented module construction. The welding method has also been extended to submerged arc welding, gas shielded welding, and manual welding. Arc welding, argon arc welding, etc., among them, the welding material is the necessary support for various methods at each stage. At present, the amount of welding materials used by major domestic shipping comp...

Problems solved by technology

However, the biggest problem with this method is that it is impossible to realize the theoretical amount of design calculation by any means, and it is difficult to determine the coefficient of addition. The accuracy of the actual amount given is not high, and the value of control reference is lost. In addition, the subsections have gone through multiple processes and multiple construction units in the actual production process, making it difficult to distinguish and manage
