In the AI era: what happens to Welders, cutters, solderers, and brazers
焊工（初級）崗位因AI驅動的自動化焊接系統在製造業、建築業中逐步普及，入門級手工焊接任務被顯著壓縮，但對複雜結構焊接與現場作業的需求仍存。
- 批量標準化金屬件的自動焊接（如車身焊接、管道接頭）
- 基於CAD模型的機器人編程與路徑規劃替代人工示教
- 焊接品質在線檢測（視覺檢測+AI缺陷識別）
- 焊接參數自動調節與焊接過程監控
- AI輔助焊接參數優化（根據材料厚度、環境溫度實時推薦電流電壓）
- 擴增實境（AR）焊接引導系統提升新手培訓效率
- 無人機/爬行機器人搭載焊接模組完成高空或危險環境焊接
- 數位孿生焊接模擬減少試件浪費
- AI驅動的多機器人協同焊接群控
- 非標工件、空間受限部位的現場手工焊接（如船上、管道內部）
- 高應力、高疲勞壽命要求的壓力容器與承重結構焊接
- 異種金屬、特殊合金（鈦、鋁鎂合金）的焊接工藝開發
- 焊接質量責任認定與返修決策
- 焊接機器人的編程與調試（如FANUC、KUKA、ABB）
- 焊接工藝模擬軟體（如Simufact Welding、SYSWELD）
- 自動化焊接質量控制與測試方法
- 數位製造基礎知識（CAD/CAM、BOM管理）
- 國際焊接工程師（IWE）等進階認證
- AR/VR焊接模擬培訓系統操作
入門焊工崗位在工廠生產線上顯著減少，自動焊接機器人已能完成簡單重複的焊接任務。新手焊工更難找到純粹的手工焊接機會，但持有6G等高級證書或具備特種材料焊接能力的焊工需求依然穩定。
從初級焊工升級為自動化焊接技師，學習機器人程式設計與離線模擬，掌握至少一種主流焊接機器人作業系統。進一步可轉型為焊接製程工程師，利用AI工具優化參數與缺陷預測，或向焊接機器人整合工程師發展，負責產線焊接單元的設計與調試。考取AWS或CWB高階認證可提升競爭力。
