用镍基填料合金对钢进行高温钎焊,要求结合间隙狭窄(小于0.004英寸)及钎焊时间长(1小时或更长)才能达到牢固结合,如果达不到这些条件,会生成脆性相并留于焊缝中从而导致机械性能降低。生产中,焊缝间隙一般为0.08英寸,要填补这种缝隙,钎焊工要添加固态材料到钎焊合金熔入焊缝 High-temperature brazing of steel with a nickel-based filler alloy requires a combination of tight gaps (less than 0.004 in.) And long brazing times (1 hour or longer) to achieve a strong bond. Failure to do so will result in brittle phases Stay in the weld resulting in reduced mechanical properties. Production, the weld gap is generally 0.08 inches, to fill this gap, braziers to add solid materials to the brazing alloy into the weld
