Has low spatter and good weld penetration, though lower than C-15 one; suitable for many steels.

Both have a very high energy density, making deep weld penetration possible and minimizing the size of the weld area.

Better weld penetration than C-25.

If the electrode is positively charged, it will melt more quickly, increasing weld penetration and welding speed.

Its addition narrows the arc and increases the arc temperature, leading to better weld penetration.

Deep weld penetration.

In addition, it allows for greater control of the weld pool, and can increase weld penetration, welding speed, and quality.

Has lower spatter and good weld penetration, suitable for thicker plates and steel significantly covered with mill scale.

Since the anode tends to have a greater heat concentration, this results in faster melting of the feed wire, which increases weld penetration and welding speed.

Argon or Argon/Helium - this raises the temperature of the arc. Welding speed is higher and weld penetration is increased.

The combination of the laser process and the arc process results in an increase in both weld penetration depth and welding speed (as compared to each process alone).

Reversing the polarity so that the electrode is positively charged (DCEP) and the workpiece is negatively charged increases the weld penetration.

Electrodes coated with cellulose, especially when combined with rutile, provide deep weld penetration, but because of their high moisture content, special procedures must be used to prevent excessive risk of cracking.

Another common shielding gas, helium, is most often used to increase the weld penetration in a joint, to increase the welding speed, and to weld metals with high heat conductivity, such as copper and aluminum.

Areas where the oxide film can break down can also sometimes be the result of the way components are designed, for example under gaskets, in sharp re-entrant corners or associated with incomplete weld penetration or overlapping surfaces.

Daigle Welding & Marine Ltd is fully certified to 47.2 by the Canadian Welding Bureau which ensures 100% weld penetration on all components and provides our customer's with absolute confidence in their boat's integrity.

Pure inert gases such as argon and helium are only used for nonferrous welding; with steel they do not provide adequate weld penetration (argon) or cause an erratic arc and encourage spatter (with helium).

All welds are full pentration corner to corner MIG welded, using a high quality inert shielding gas and level layer wound MIG wire to ensure good welding penetration and exclusion of porosity in the weld.
