How to Weld Steel Pipes
By Tricia Lobo
Welding
pipes is one of the simplest and most durable ways to join piping together and
steel pipes can simply be welded together with MIG (metal inert gas), TIG
(tungsten inert gas or SMAW (stick metal arc) welding.
Before
welding two pipes together, avoid any gaps between the two pipes. While
welding, take measures to ensure the continual alignment of the two pipes.
Align
the two pipes and use clamps to hold them together, if necessary.
Fire
your welding torch or strike your welding electrode on the steel to open an arc
between the welding tool and pipes.
Allow
the torch to form a small welding puddle on the surface of the steel, called a
tack weld.
Move
the arc slightly and create another welding puddle elsewhere on the
circumference of the pipes.
Continue
to move the arc and create more welding puddles until you have formed a series
of tack welds at regular intervals along the circumference.
Move
the welding tool thoroughly along the circumference of the pipes creating a
welding puddle that extends fully around the circumference and connects the two
pipes together.
Extinguish
the arc and allow the welding puddle several minutes to dry.

engineering research, "Biocompatible and pH sensitive PLGA encapsulated
MnO nanocrystals for molecular and cellular MRI," was accepted in 2010 for
publication in the journal "Nanoletters." Lobo earned her Bachelor of
Science in biomedical engineering, with distinction, from Yale in 2010.
