The waxwill causepoor weld penetration , as well as bead

Superior welding from AWS certified weldersresultsin better weld penetration with less weld spatter

often(passive) is ... causedDamage at weld seams

a coatingcould be causingweld penetration problems

the heat and weld puddleresultingin poor weld penetration and poor weld strength

by short circuit(passive) caused bybad line welding

Because of the small hole filled with high temperature steam , it is beneficial to the stirring of weld pool and gas escapingresultingin the formation of no hole penetration welding

Use of incorrect gasmay leadto little or no penetration of welding bead

of incorrect gasmay leadto little or no penetration of welding bead

Normally , the aluminum base metal pulls heat away from the arc startcausinglack of penetration at the beginning of the weld

a lower melting pointcan causesome trouble while welding

increases the arc temperatureleadingto better weld penetration

The use of helium as shielding gasresultedin better weld penetration

effectmay resultin deep narrow weld penetration

the weld poolcausingdeep narrow weld penetration

as shieldingresultedin better weld penetration

Too much sulfurcausesa lack of penetration of the orbital welding

the addition of nitrogen and oxygen to the argon shielding gasresultedin better weld penetration

The earth movementsmay causewelding seams to break

The large arc forceledto big weld penetration

Incorrect contact timeswill resultin poor solder penetration
