Weld Process Training Cheat SheetKeep this in your tool box for future reference.
To view this slide presentation and video in its entirety contact Paul W. Cameron – Weld Engineer at 6163 or [email protected] training is estimated to be 2 to 2 ½ hrs in length.
Short Circuit -When should I use it?
• Low current, Low voltage– Use on material 3 mm or less
– Use for welding Vertical up or Vertical down
– Use on gaps and open roots
• Never use on material over 5 mm (exceptvertical up).– Poor side wall fusion can occur.
Spray Transfer -When should I use it?
• Material 3mm or more
• Flat and Horizontal only– except vertical down on material under 5mm.
• Caution - Poor fusion can result from…– Horizontal fillet welds greater than 6mm.
– Manual welders using whipping or weavingtechniques.
• Limit single pass, horizontal welds to 8mm.
Globular Transfer -When should I use it?
• Beneficial in bridging gaps on heavymaterial.
• Evident when the ball that forms on the tipof the wire is larger than the wire.– This large ball creates poor arc starts.
• Weld Spatter is the primary negative affect.
• AVOID GLOBULAR TRANSFER!
Mig Welding Parameters -The Clock Method
• View a traditional wire feed control like aclock with ten settings
Mig Welding Parameters -The Clock Method
• On average, Wire Feeders deliver 700 ipm– Traditional Feeders deliver 600 to 800 ipm
• Feeders usually operate within ten setting.– between 7 and 5 o’clock– 700 ipm 10 = 70 ipm each
• 12 o’clock = the 5th setting– 5 x 70 ipm = 350 ipm
Mig Welding Parameters -A Simple Check
• Double check your Wire Feed Speed– Set your feeder at its highest speed setting.
– Pull the trigger for 6 seconds.• Insure the wire won’t come in contact with the
work.
– Measure the amount of wire that came out in 6seconds.
– Each clock position will increase Wire FeedSpeed by the amount you measured.
