Weld anti-spatter compound and its preparation method

Abstract

The present invention relates to chemical paint and is especially one kind reagent painted to the metal surface to prevent splash. The splash preventing agent consists of rutile powder 10-20 wt%, calcium nitrate 1-6 wt%, iron-vanadium-aluminum powder 5-10 wt%, zinc oxide 2-8 wt%, ferric manganese phosphate 2-8 wt%, butyl cellulose 8-20 wt%, light calcium carbonate 2-8 wt% and modified ethanol 20-70 wt%. Applying the splash preventing agent makes the welded plane maintain smooth and no damage, and this can omit the polishing with grinding wheel after welding and ensure the reliability of ultraviolet detection.

Description

Technical field: [0001] The invention relates to a chemical coating, and the anti-splash agent refers to a reagent used to prevent spatter on the surface of metal after welding. Background technique: [0002] Welding construction is a process widely used in modern industry. For example: marine ships, aerospace, railway transportation, petrochemical industry, boiler containers, hardware construction, etc., there are welding occasions everywhere. [0003] The metal that is partially melted during welding is generally the welding rod and the two pieces of metal that are expected to be connected, also known as the base metal. The three are melted locally, and the mixture often has external gas or non-metallic inclusions mixed in. The released gas, due to the high temperature of the arc generated by the high current, explodes due to the rapid temperature rise, and throws some liquid metal into the air with a crackling sound. They shine because of the high temperature and fly aro...

Problems solved by technology

Ultrasonic testing on such a surface will not only damage the expensive probe, but also consume a large amount of ultrasonic energy on the rough surface, which will greatly reduce the sensitivity of ultrasonic testing. These dangerous defects cannot be found, and the consequences are unimaginable

[0007] The method of not using grinding has not yet been proposed, even in some authoritative specifications such as the International Institute of Welding (IIW) and the American ASME 1998 BOILER AND PRESSURE VESSEL CODESection IX-Welding. is not possible
