The invention relates to a welding technique, in particular to a wear-resistant material surfacing method achieving preheating temperature lowering.The technical problems that an existing surfacing method is high in welding temperature and welder replacing frequency are solved.The wear-resistant material surfacing method achieving preheating temperature lowering comprises the following steps that a workpiece is preheated to 120 DEG C or above before a transition layer is surfaced, then 309 MoL is surfaced on the transition layer, the surfacing thickness is 2.5-3.5 mm, 100% PT detection is performed after the transition layer is surfaced, and part stress elimination heat treatment is performed after the transition layer is qualified; a surface layer is surfaced, the workpiece is preheated to 120 DEG C or above before the surface layer is surfaced, a STELLITE 6 phi 4 welding rod is selected when the surface layer is surfaced, the surfacing thickness is 3-4 mm, and welding rod arc welding is adopted as a welding method of the surface layer; 100% PT detection is performed through reacting after the surface layer is surfaced, heat treatment is performed after the surface layer is qualified, and after the temperature of the workpiece is lowered to 400 DEG C along with a furnace, the workpiece is taken out from the furnace, and heat preserving and slow cooling are performed.According to the method, the preheating temperature can be obviously lowered, therefore, the labor intensity of a welder is reduced, and a large quantity of resources for heating the workpiece are saved.
Description
Technical field
The present invention relates to solder technology, be specially a kind of high-abrasive material overlaying method reducing preheating temperature.
Background technology
Traditional overlaying method, require preheating temperature >=350 DEG C, and temperature >=350 DEG C between controlling, temperature between complicated frock and substantial amounts of Resource Guarantee road is needed during built-up welding, for large-area built-up welding, joint environment temperature is at a relatively high, then need altofrequency to change welder and carry out built-up welding, to ensure that welder's health is in health status.This welding method efficiency is low, and health is unfavorable.Therefore a kind of overlaying method being able to ensure that health, raising welding efficiency it is highly desirable to.
Summary of the invention
The present invention solves that the welding temperature that current overlaying method exists is high, change the technical problem that welder's frequency is higher, it is provided that a kind of high-abrasive material overlaying method reducing preheating temperature.
It is an object of the invention to, front lower in the premise ensureing surfacing quality, reduce welder labourer's intensity, reduce resource consumption.
The present invention realizes by the following technical solutions: a kind of high-abrasive material overlaying method reducing preheating temperature, comprises the following steps:
(1) before transition zone built-up welding, workpiece being preheated to more than 120 DEG C, the 309MoL of transition zone built-up welding afterwards, built-up welding thickness is 2.5～3.5mm, and transition zone heap is soldered laggard row 100%PT detection, carries out parts hidden lino removal after qualified；
(2) carrying out surface layer built-up welding, before surface layer built-up welding, workpiece is preheated to more than 120 DEG C, STELLITE6 is selected in surface layer built-up welding4 welding rods, built-up welding thickness is 3～4mm, and its welding method is SMAW；Surface layer heap should carry out 100%PT detection after being soldered, and carries out heat treatment, insulation slow cooling of coming out of the stove after being cooled to 400 DEG C with stove after qualified；
Between transition zone, surface layer heap welding bead, temperature is not less than preheating temperature.
Stellite6 is a kind of cobalt base hard alloy resistant to all kinds abrasion and corrosion and high-temperature oxydation.It is widely used in pressure vessel, aero-jet engine, industry gas turbine, the guide vane of Vessel personnel and nozzle guide vane and diesel nozzeles.
The present invention adopts Stellite64 welding rod built-up welding surface layers, carry out transition in conjunction with 309MoL wlding, preheating temperature when greatly reducing built-up welding and temperature between road；The built-up welding thickness of transition zone and surface layer can ensure that the quality after welding, and heat treatment process can effectively eliminate stress.
Further, transition zone, surface layer heap welding bead between temperature all at 120～200 DEG C.
Between road, temperature selects said temperature scope to can ensure that the welding quality under lower temperature.
Further, the welding method of transition zone built-up welding can adopt submerged arc band pole automatic welding, automatically/manual gas shield welding, SMAW.
Further, adjacent two welding bead amounts of lap are between 60 ~ 75%, to ensure thickness in monolayer >=3mm.
Further, overlay cladding thickness should be uniform, and the thickest and the thinnest difference is not more than 1mm.
Adjacent two welding bead amounts of lap and overlay cladding thickness can ensure that and still may insure that under relatively low welding temperature welding quality meets technological requirement.
The present invention can substantially reduce preheating temperature, makes labourer's intensity of welder be minimized, saves the resource of a large amount of heated parts.
Detailed description of the invention
1, the objectionable impurities such as the rust of facing surface, greasy dirt and moisture content are treated in cleaning, it is desirable to facing surface must not have the defects such as crackle；And carry out 100%MT detection, I grade is qualified；
2, tackle workpiece before transition zone built-up welding and be preheated to more than 120 DEG C, transition zone built-up welding 309MoL, built-up welding thickness is 2.5～3.5mm, and its welding method can adopt submerged arc band pole automatic welding, automatically/manual gas shield welding, SMAW according to workpiece shapes size, and postwelding heat-preservation cotton covers slow cooling；
3, transition zone heap should carry out 100%PT detection after being soldered, and carries out parts hidden lino removal (heat treatment temperature is fixed according to base material) after qualified；
4, after heat treatment completes, harmful foreign material on cleaning transition zone surface, then carry out surface layer built-up welding, tackle workpiece before surface layer built-up welding and be preheated to more than 120 DEG C, adopt SMAW, select STELLITE64 welding rods carry out built-up welding.Built-up welding thickness is 3～4mm；Postwelding heat-preservation cotton covers slow cooling；
