What 溶接工 do

An English description is being prepared. Japanese description:

熱を利用して金属材料を接合する溶接を行う。
 溶接は、その接合の仕方により「融接」、「圧接」及び「ろう接」に分類される。
 ここでは最も広く利用されている融接について記載する。被溶接材(母材)の接合しようとする部分をガス炎、アーク、電子ビーム、レーザーなどの熱を用いて加熱し、母材と溶加材(溶接棒、ワイヤなど)を融合させてできた溶融金属を凝固させて接合する方法である。この接合方法では、アーク熱を利用して行うアーク溶接が最も一般的で、超高層ビル、工場や住宅などの建築物、橋、タンクや容器、ガスや石油などのパイプライン、船、発電設備などを作るときの金属材料の接合に利用されている。
 溶接方法としては手溶接、半自動溶接、自動溶接がある。
 手溶接の場合は、溶接棒を溶接棒ホルダにはさみ、適正な溶接電流、電圧などを調整して、これを接合する金属材料に接触させるとアークが発生し、溶接棒と金属材料が溶融するので、溶接棒を手で動かす(運棒)ことで溶接を行う。
 半自動溶接の場合は、溶接棒の代わりに自動的に送給されるコイル状のワイヤを溶接トーチにつないで溶接を行う。
 自動溶接の設備を用いる場合には、設備を運転、操作して電熱・電撃・ガスの炎などを利用した金属の接合、切断の工程の監視、調整を行う。
 溶接によって製作した製品は、検査を行って溶接部の内部に欠陥がないか調べ、溶接部の性能を確認して品質の確保を行う。

◇ よく使う道具、機材、情報技術等
 溶接棒、溶接棒ホルダ、溶接トーチ、自動電撃防止装置、工具(手動工具、電動工具)、作業中の保護具(ヘルメット、ゴーグル、グローブ、安全靴等)
