How to optimize the welding parameters of ER5087 welding wire? Comparison of pulse MIG and TIG processes

1. Key points for optimizing welding parameters of ER5087 welding wire

1. Factors affecting core parameters

Current/voltage
MIG process: higher current (180-250A) and voltage (18-24V) are required to ensure the penetration depth, but excessive current should be avoided to cause burn-through (pulse MIG is recommended for thin plates).
TIG process: DC positive connection (DCEN), current range 150-200A, more precise control, suitable for thin plates or precision welding.

Wire feeding speed (MIG)
Positively correlated with current, usually 4-8m/min, needs to match the fluidity of the molten pool (magnesium and aluminum are easy to oxidize, and need to be slightly faster than steel welding wire).

Shielding gas
Recommended mixed gas: Ar+30-50% He (He increases heat input and improves penetration depth); pure Ar can be used for thin plate TIG.
Flow rate: 15-20L/min (MIG requires higher flow to prevent air holes).

2. Optimization of process adaptability

Advantages of pulse MIG:
Reduce heat input, reduce magnesium evaporation and deformation, suitable for medium and thick plates (such as automobile chassis).
Parameter example: base current 80A/peak current 220A, frequency 50-100Hz.

Advantages of TIG:
No spatter, beautiful welds, suitable for precision aerospace parts (such as cabin sealing welds).
Requires high-frequency arc initiation and delayed gas stop (to protect the magnesium-aluminum molten pool).

2. Comparison of pulse MIG and TIG processes

Comparison Aspect Pulse MIG TIG
Heat Input Medium (controlled pulse reduces peak heat) Low (ideal for thin plates, small HAZ)
Welding Speed Fast (suitable for automation and mass production) Slow (manual operation, precision-oriented)
Penetration Control Deeper (with He mixed gas assistance) Shallow and uniform (requires multi-pass for thick plates)
Equipment Complexity High (requires pulse power source, wire feeder) Lower (but needs skilled operator)
Common Defect Prevention Porosity (requires strict gas shielding) Cracking (preheat to 120°C reduces cold cracking risk)
Typical Applications Automotive structural parts, medium-thick plate mass production Aerospace precision components, thin plate repairs

3. Practical suggestions

Material pretreatment
Thorough cleaning (acetone degreasing + stainless steel brush to remove oxide film), welding in an environment with humidity <60%.

Parameter debugging steps
MIG: first fix the wire feeding speed and adjust the current until the molten pool is stable;
TIG: start from low current and observe the wettability of the molten pool.

Process selection decision tree:
Mass production/medium and thick plates → pulse MIG (high efficiency);
Precision/thin plates/repair welding → TIG (quality first).

4. Industry Application Cases

Automobile Lightweighting: A car company uses pulsed MIG (ER5087+Ar/He) to weld magnesium-aluminum door frames, increasing welding speed by 30% and deformation <1mm.
Aerospace tanks: TIG process is used to weld 2mm thick magnesium-aluminum alloy, and copper pads are added on the back to achieve zero-defect X-ray inspection.
