| The following are all welding techniques used in our custom plastic fabrication shop: |
• Extrusion welding
is ideal for larger welds in a single pass as it draws welding rod into
a hand held plastic extruder that heads the material with hot air to
allow bonding to take place.
|
• Freehand welding uses heated welding rod and a jet of hot air on the weld area at the same time.
|
• Heat sealing is the process of sealing one plastic to a similar plastic using heat and pressure.
|
• Hot gas welding (also known as hot air welding) uses heated welding rod.
|
• Injection welding is the same as extrusion welding.
|
• Ultrasonic
welding is the quickest welding procedure available. High frequency (15
kHz to 40 kHz) low amplitude vibration creates heat by way of friction
between the materials to be welded.
|
• Speed tip welding is similar to a
soldering iron as the welder is fitted with a feed tube for the welding
rod. The speed tip heats the rod while it is being pressed into the
position being welded leaving a bead of softened plastic.
|
• Spin welding is a form of frictional
welding where one round piece is held still while a similar one is
rotated at high speed the whole time being held lightly against the
stationary piece.
