A suitable fusion welding method is gas-shieldedarc welding, with the TIG method as first choice.IPCO (略)SA的焊缝可以达到优异的强度及韧性。 推荐使氩弧焊Since the material has low thermal conductivity and high thermal expansion, welding should be carried out with a low heat input, to avoid distortion. Rapid cooling is required to prevent carbide precipitation in the heat-affected zone.由于母材的低导热率及高膨胀率，建议低电流焊接，避免变形。同时要求焊接后迅速降温。Welding is normally performed without welding wire. In case of using wire, wire type should be IPCO (略)SA (AWS A5.9 ER (略) LSi). In order to increase the flatness and strength of the weld, cold working is recommended.一般推荐无焊丝焊接，如果需要添加焊丝，需使用IPCO (略)SA (AWS A5.9 ER (略) LSi)牌号焊丝。Further information concerning method and equipment etc.required can be obtained from your local IPCO office.更多的技术信息请咨询当地IPCO分公司<img width=(略) height=(略) src=http：(略)<img width=(略) height=2 src=http：(略)</div><img width=(略) height=(略) src=http：(略)<img width=1 height=8 src=http：(略)<img width=1 height=8 src=http：(略)<img width=3 height=1 src=http：(略)<img width=3 height=1 src=http：(略)<img width=5 height=1 src=http：(略)<img width=5 height=1 src=http：(略)<img width=(略) height=9 src=http：(略)<img width=9 height=8 src=http：(略)<img width=6 height=9 src=http：(略)<img width=6 height=8 src=http：(略)<img width=(略) height=8 src=http：(略)<img width=2 height=2 src=http：(略)<img width=2 height=2 src=http：(略)<img width=6 height=8 src=http：(略)<img width=(略) height=(略) src=http：(略)</div> (略)-(略)-(略)来源：(略)
