说明：WD-612焊剂是硅钙型烧结焊剂，碱度约1.0（BIIW），配合低碳和超低碳不锈钢焊带，用于在低碳钢和低合金钢上不锈钢过渡层的电弧带极堆焊。为了防止铬的过量烧损，焊剂中含有一定量铬以补充烧损。
用途：用于化工容器、加氢反应器内壁及管板的不锈钢过渡层的电弧带极堆焊。
焊剂参考成分（%）：
堆焊金属化学成分：
注意事项：
1、焊剂如果受潮，在使用前须经300~350℃烘焙2小时。
2、焊接处须清除铁锈、油污、水分等杂质。
WD-612 Agglomerated Flux For S.A. Welding
Standards: GB/T 17854-1999 F309-H0Cr24Ni13 F308L-H00Cr24Ni13
Introduction
WD-612 is an agglomerated calcium-silicate type flux with a basicity index of BIIW 1.0.Matching low-carbon and extra-low-carbon stainless solder strip,WD-612 can be used for band arc hard surfacing in the stainless steel transition layer of low-carbon and low-alloy steel. In order to prevent the excess burn-out of chromium, a certain amount of chromium should be contained in the welding flux as a supplement of the burn-out.
Applications
Band arc hard surfacing in the stainless steel transition layer of the inner wall and pipe plate of pressure vessels for the chemical industry and hydrogenation reaction chamber.
Main Constituents (%)
Typical chemical composition of deposited metal (%)
Notice:
1. Flux should be redried at 300~350°C for 2 hours.
2. All dust, oil and rust should be removed.
