Add You - Welding Defects - How to Prevent Them!
How important are staff to your business? That’s sort of a basic question, because everyone knows that without staff you can’t do your own job. But really, how important do we consider our staff? After all, they haven’t been to school as long as we have, they don’t know as much, they don’t make the money we do. Shouldn’t it be easy to replace th
Undercutting is another problem that causes welding defects. It burns away the base metal at the toe of the weld. It's caused by a current adjustment that is too high; an arc gap that is too long or failure to fill up the crater completely with weld metal.
Porosity looks "sponge like," or like tiny "bubbles" in the weld. It's caused by gases being
Integrity is one thing that stands strong when everything else falls apart. What goes around comes around. So many of us could have been successful today if we had been honest with ourselves. As an internet marketer sometimes I am tempted to over exaggerate in order to make quick sales but I have come to discover that most successful people onlin
To minimize the chance of welding defects be sure to consider 1) the travel speed of the pass; 2) the size and type electrode; 3) machine settings; 4) make sure the welding is done in accordance with the plan and the current conditions.
Most of, or a great deal of, welding defects can be identified by the "naked eye." By knowing what is likely to produce welding defects you will learn how to avoid them. Production without defects saves time, materials, repair costs, and a decrease in productivity.
The two following causes for weld rejection should not be but are often overlooked 1) is the weldor proficient with the process being used? 2) is the welding rod supply up to standards? Use only properly stored, dried, and maintained welding rods.
Welding defects include poor penetration. It's the failure of the welding rod and base metal to fuse together. It's caused by a root face that is too big; a root opening that is too small; an electrode that's too large; slow travel speed or a machine setting that's too low.
Poor fusion is the failure to blend the layers of weld metal together with the base metal. A lack of fusion is caused by " . . . failure to raise to the melting point of the base metal or the deposited weld metal," (Miller Electric Mfg. Co.) It's caused by improper fluxing; dirty plate surfaces; improper electrode size or type; wrong current settings. Electrodes that do not meet the storing, drying and maintenance specifications also cause it.

A resume is something that advertises you in front of your future boss; think it as a tool that will enhance your qualities and professional appearance. It is very important to know how to create and use that good tool, what mistakes to avoid when creating one and how to make a good impression.Think about it as a business card, if it’s nice

Don't underestimate the power of prototyping. Too often the benefits of prototyping an invention are either played down or completely ignored when "experts" take to the issue. But turning your idea into a product sample is probably the most important part of inventing. And if you're not convinced here are five reasons why you should prototype your

Porosity looks "sponge like," or like tiny "bubbles" in the weld. It's caused by gases being released by the cooling weld because a current setting is too high or arc is too long.
Slag inclusion occurs when the slag is not chipped and cleaned properly and then another pass is made over the top. To avoid, 1) prepare the groove and weld properly before each pass; 2) thoroughly clean in between passes; check the machine settings against those suggested by the manufacturer; 3) hold a smaller weld puddle.
