Problems solved by technology
[0002] In the existing solid welding wire standard, only the chemical composition of the welding wire itself and the physical properties of the deposited metal are standardized, but the solid welding wire also involves the wire feeding performance of the welding wire in the user's application. The welding conditions are consistent, and in order to improve the welding wire to meet the welding requirements of the construction site, it is necessary to formulate corresponding evaluation standards for welding wire feeding performance

The invention discloses an evaluation device and an evaluation method for wire feeding stability of a solid welding wire, wherein the evaluation device comprises a base, a pillar, an adjusting arm and a welding gun fixing device; the pillar is fixed on the base and is provided with a sliding block, and the adjusting arm is horizontally arranged; and the evaluation method comprises the following steps: fixing the welding gun at a clamping part, wherein a spraying port of a spray gun is over against a bullseye for spraying and target practice times are 20; describing a circle with a diameter of 10mm by taking the bullseye as a circle center, circling target points as much as possible, observing the number of the target points falling inside and outside the circle, and evaluating. The evaluation device and evaluation method have the advantages that most welding conditions at a welding construction field, even a welding state in a full automatic welding process can be simulated, standardized evaluation on the wire feeding performance of the welding wire is realized, products with higher quality are provided for a client, the evaluation method for the wire feeding stability of the solid welding wire is made, and the blank of the welding wire in the aspect of process performance evaluation is filled up.
Description
technical field [0001] The invention belongs to the field of welding rod production, and in particular relates to a solid welding wire feeding stability evaluation device and evaluation method. Background technique [0002] In the existing solid welding wire standard, only the chemical composition of the welding wire itself and the physical properties of the deposited metal are standardized, but the solid welding wire also involves the wire feeding performance of the welding wire in the user's application. The welding conditions are consistent, and in order to improve the welding wire to meet the welding requirements of the construction site, it is necessary to formulate corresponding evaluation standards for the wire feeding performance of the welding wire. Contents of the invention [0003] The problem to be solved by the present invention is to provide a solid welding wire feeding stability evaluation device and evaluation method to solve the above problems. [0004] I...
