Ag Power Welding Unit

if only one kind of electrode for general arc welding on the farm to be used, the best choice is

E6011

when metal is prepared for welding it should be

clean

It is important to identify galvanized steel because

it gives off poisonous gas when heated

when welding a metal project without electrical power what type of carc welder should used?

DC

what is used to protect eyes of a welder from light rays

welding helmet

what type of electrode is most commonly used when welding farm projects

E6011

what wire welder is used in industry as an automatic welder

MIG

an advantage of a DC welder is

it can be used without regular power line electricity

what welder produces a weld that is stronger and freer of corrosion than other welders?

TIG

an electric arc welder is used to weld

metal

the proper tool for removing slag from a weld is

a chipping hammer

constructing and repairing steer from farm equipment by melting and joining the edges of metal pieces are done by using

arc welding

the 2 most commonly used general purpose electrodes for welding are

E6011 and E6013

the TIG welding process uses non consumable electrode and

helium or argon

if students weld 2 pieces of metal end to end in the flat position, what type of weld is this?

butt

when preparing metal for welding what is the fastest way to clean metal

grind

what is the proper procedure to use if an electrode sticks to metal

(profanity) move electrode holder back and forth)

metal thickness, electrode size, and welding position are used to decide the

amperage setting

when barry started welding there was a lot of spatter, his bead was flat, what caused this?

amperage was too high

neal is making a welding project, before he starts what should be do to the metal?

identify and clean

if the travel speed is too fast the welded bead is

narrow

an amperage setting that is too low will cause

high and narrow beads

why should a person wear leather gloves when welding?

prevent burns

to help prevent fired the welding area should be clear of

combustible materials

what kind of fillet weld joint is made when 1 piece of metal is over another and joined?

lap

if a bead welded with MIG is too narrow what should you do?

decrease weld speed

the size of an electrode is determined by the

diameter of the bare end of the rod

which welding process requires a mixture of flammable gasses

oxy-acetylene

what metal is an electrode will improve a welds appearance

chromium

what factors will determine the penetration of a SMAW weld?

thickness of metal, type of welding process, amount of heat, and type of electrode

which materials will increase the strength if a weld

silicone and manganese

which is the first step in the fabrication process

research prototype criteria
