Description
本発明の方法は、Usibor 1500(登録商標)すなわち重量でそれぞれの割合が90%及び10%である30μmのアルミニウム/ケイ素(Al/Si)の層で被覆された鋼製部品を手動でMIGアーク溶接を実施する間に良い結果を得た。
溶接部は、それぞれ1.2mmの厚みを有している。
実施された試験の状況において、20l/minの流量及び4barの圧力で配分される使用されるガス(容積%)は、以下のとおりである。
− 試験B(発明):アルゴンと2%の窒素(N2)で形成された混合物
− 試験C(発明):アルゴンと4%のN2で形成された混合物
− 試験D(発明):アルゴンと6%のN2で形成された混合物
− 試験E(発明):アルゴンと8%のN2で形成された混合物
− 試験F(比較対照):アルゴンと8容量%のCO2で形成された混合物。
溶接電圧は約15V、溶接電流(intensity)は約280A;これらは、Air Liquide Welding France社製のDigi@wave 400タイプ(短アーク/短アーク+)共同モード(EN131)の発電機によって得られる。達成された溶接速度は、20cm/minである。
以下に、本願の補正前の特許請求の範囲に記載された発明を付記する。
[1]
金属部品の金属の溶融をいかなるレーザービームを除いて唯一アーク放電によって行ない、シールドガスを使用して、アルミニウムを主成分とする表面被膜を含む少なくとも1つの金属部品をアーク溶接する方法であって、前記シールドガスは、アルゴン及び/又はヘリウムと、窒素との混合物からなることを特徴とする方法。
