X Semi-automatic welding

X.1 Characteristics of semi-automatic welding
X.1.1 Semi-automatic welding using gas cylinder

• Semi-automatic CO_ {2} welding
  • Filling fluid: CO_{2}
  • Usage: Mainly metal
  • Sputtering: Many
  • Wind effect: Yes
  • Cost: Low price / other gas cylinder rate

• Semi-automatic metal inert gas welding: MIG
  • Filling fluid: Ar + O_{2} / O_{2}: 2 [\%]
  • Usage: Mainly aluminum and stainless steel
  • Sputtering: Very low
  • Wind effect: Yes
  • Cost: Low price / other gas cylinder rate

• Semi-automatic metal active gas welding: MAG
  • Filling fluid: CO_{2} + Ar / 20 [\%] + 80 [\%]
  • Usage: Mainly metal
  • Sputtering: Less
  • Wind effect: Yes
  • Cost: Low price / other gas cylinder metal

• Non-gas welding
  • Welding by electric power
  • Usage: Mainly metal
  • Sputtering: Many
  • Wind effect: No
  • Cost: Expensive
