Key cautions關鍵注意事項

Sustained heat (above ~65 °C):長期高溫(約 65°C 以上): High-magnesium 5xxx welds (5083 / 5356 / 5183) can become sensitive to stress-corrosion cracking in continuous warm service. For these conditions, use the lower-magnesium 5454 / ER5554 system.高鎂 5xxx 焊縫(5083 / 5356 / 5183)在連續高溫使用時,可能對應力腐蝕較敏感。此類工況請改用低鎂的 5454 / ER5554 系統。
Anodize color match:陽極配色: ER4043 anodizes dark grey; ER5356 stays close to the base color. Choose ER5356 where the weld will be anodized and appearance matters.ER4043 陽極後偏深灰;ER5356 接近母材色。焊縫需陽極且重視外觀時,選 ER5356。
Strength vs. crack resistance:強度 vs 抗裂: Silicon fillers (ER4043 / ER4047) flow well and resist cracking; magnesium fillers (ER5356 / ER5183) give higher as-welded strength. Match the filler to what the joint needs most.矽系焊材(ER4043 / ER4047)流動性佳、抗裂;鎂系焊材(ER5356 / ER5183)焊態強度較高。依接頭最需要的特性選配。
Feed consistency:送線一致性: On automated and robotic MIG lines, inconsistent wire diameter causes feed slips and porosity. GOLDING supplies all grades on precision layer-wound 7 kg spools, engineered toward a ±0.01 mm diameter tolerance.在自動化與機器人 MIG 產線上,線徑不均會造成送線打滑與氣孔。GOLDING 全系列以精密層繞 7kg 線盤供應,以 ±0.01mm 線徑公差為精度目標。

Frequently Asked Questions常見問題

What filler metal should I use for 6061 aluminum?6061 鋁該用什麼焊材?
ER4043 is the most common choice for 6061 — it resists cracking and feeds smoothly on automated lines. Use ER5356 when you need higher joint strength or a color match after anodizing.ER4043 是 6061 最常用的選擇——抗裂、在自動化產線送線平順。需要更高接頭強度,或陽極處理後要配色時,改用 ER5356。
Can I weld 5083 with ER4043?5083 可以用 ER4043 焊嗎?
No. 5083 is a high-magnesium alloy; ER4043 produces a brittle, low-strength joint. Use ER5183 (the best match) or ER5356.不行。5083 是高鎂合金,ER4043 會形成脆、低強度的接頭。請用 ER5183(匹配最佳)或 ER5356。
Which aluminum filler matches anodized color best?哪種鋁焊材陽極後配色最好?
ER5356 anodizes close to the base aluminum, while ER4043 turns dark grey. Choose ER5356 wherever the weld will be anodized and appearance matters.ER5356 陽極後接近母材色,ER4043 則偏深灰。焊縫需陽極且重視外觀時,選 ER5356。
What aluminum filler should I use for high-temperature service?高溫工況該用什麼鋁焊材?
For sustained service above roughly 65 °C, avoid high-magnesium 5xxx fillers (5083 / 5356 / 5183), which can be sensitive to stress-corrosion cracking. Use the lower-magnesium 5454 / ER5554 system instead.約 65°C 以上長期使用時,避免高鎂 5xxx 焊材(5083 / 5356 / 5183),它們對應力腐蝕較敏感;改用低鎂的 5454 / ER5554 系統。
