How to use alloy powder for Spraying


Chengdu WOCO carbide Industry Co.,Ltd

     which was established in the hometown of hard metal of China--- ChengDu city in Sichuan province. A professional Chinese manufacturer of tungsten carbide products such as drawing die,indexable inserts shims, drilling bits, drawing dies, cold forging dies, carbide bars, carbide rods, carbide balls, carbide burrs, etc. Along with our company growth, we hope to build business with more companies abroad

According to the predetermined formula weighing various alloy alloy powder and mixing,QH-2/h alloy powder spray spray torch in dual-use material Q235,size 100 mmx50 specimen of mmx16 mm,0.4~0.5 mm coating thickness control, ensure that the content of deposited metal alloy. In 100~150 alloy powder particle size control,influence alloy powder is too thick-alloy powder spray; too rules in hardfacing alloy powder burning in the process increases. Spraying process parameters such as oxygen pressure 0.5~0.8 MPa,0.05~0.07 acetylene pressure MPa, nozzle distance of 150~200 mm from the work piece surface, before spraying the specimen surface rust going to oil disposal.
 
1.3 (CO2+N2) protection arc heap welding process try pieces surface spray alloy powder Hou again for (CO2+N2) protection arc heap welding,heap welding method and process parameter and General solid CO2 heap welding similar, this test used φ 1.2 mm apples of H08Mn2SiA wire, CO2 gas flow 11 L/min, nitrogen flow 1.5 L/min,CO2 and N2 through their of valve and flowmeter into gas mixed room uniform mixed Hou import torch of into tracheal road,19 v arc voltage, welding current 135 a. Heap welding Shi needed note following points:
 
1.welding process in the arc as through powder layer Center, guarantee alloy powder full fusion.
 
2.welding road more wide, torch needed horizontal swing,guarantee alloy powder completely fusion, get more wide of heap welding layer.
 
3.heap welding speed on heap welding layer alloy content has larger of effect,can through test determine,if used automatically welding on better master.
 
4.heap welding best added introduction arc Board and out arc Board, because introduction arc and out arc at easy produced alloy powder fusion bad, and stomatal and clip slag, defects.
