AWS

Well, Spring is finally here and of course this means the annual AWS welding show will commence April 26th thru April 28th in Dalas Texas. Check out the agenda here. Postle Industries will not have a booth this year, but we will be there. Contact us and we will make arrangements to meet with you.

Payoff Wire From Stationary Packs

For many years, both solid and cored wires in drums have been payed off from a lazy susan. This ensured consistent wire of the right cast and helix delivered to the arc. The result of course is that there is no wire wander. Some time ago Postle incorporated a new type of Pack that did not require a lazy susan, particularly for small diameter wires. Wire is laid in the Pack much the same way you would coil a garden hose on the ground. It is then taken out of the Pack in very same manner. An insert is placed on top of the coils to keep them in place and a cone section is mounted on top of the pack to ensure an even feed vertically. The system works great and all you need to do is set the pack on the floor and you're ready to weld ---- no lazy susan.

Well, that is not always true, as I recently discovered with a valued customer. There are some applications that require PRECISE placement of the deposit and it cannot deviate, even the least little bit. The customer is placing a bead on a 1/4" wide base plate edge for about 3 inches. The fact that it is a MIG Carbide application complicates the matter even more. Paying off an 0.045" diameter wire with the new system proved to be unacceptable regardless of the setup and parameter tweeking. Wire wander, even as small as it was, would not deposit the bead precisely on the the thin edge. Only when the pack was rotated with a lazy susan were deposits acceptable. Absolutely no wire wander. The customer's application may be a rarity but it nicely illustrates that a lazy susan can pay off the wire with this type of package and for applications that require precise control. The lazy susan is still the wisest choice. So, if you have been using our old packaging and want to switch to a stationary pack and pay off through a cone, you can now do this. But if you want to stay with the lazy susan there is no problem, you can still do it, without fear of changing your setup.

We now incorporate this new packaging in all wires smaller than 5/64" dia. All larger sizes are still packaged for a lazy susan and should not be used with a stationary pack and cone. The wire will twist and cause deposits to look ropy and unacceptable. There is an exception to this rule, as there are to most rules. Large diameter wires run with a very short stickout will usually not display a ropy bead.

Evaluating Wear Mechanisms

It has been said that 80% of all wear is abrasive in nature. From my experience it appears to be pretty accurate. This would lead to a rather simple solution to solving wear problems, since the cause is usually abrasive. Wish it were that easy. But then again, some of us wouldn't have jobs if it were that easy. Allow me to take some liberties here and requote that statement. "80% of all wear is PREDOMINATELY abrasive in nature". Notice the catchword "PREDOMINATELY". It has been my experience that most wear is a combination of wear mechanisms which may include one or more of the following: * Corrosion * Erosion * Metal to Metal or Adhesive Wear * Impact * Galling * Thermal Fatigue * Abrasive Wear. It is the "Other" wear mechanisms in combination with abrasive wear that causes all the problems. It is only until the other mechanisms are recognized that a successful solution to the wear problem can be achieved. The identification process can be very difficult because of the subtle nature of the "Other" mechanisms. Impact, for example is often undetected or underrated. Think for a moment about water dripping from a rock crevice onto a rock ledge. Doesn't appear that would create any impact at all, but it is the major wear factor from the rock ledges viewpoint. Huge gullies are formed in this manner. Some forms of Erosion for example, can be caused by minute gas bubbles bursting and causing impact on a metal surface. This can result in extensive damage. Actually the list of "Other" wear mechanisms goes on. The point here is that, when evaluating a wear problem, look for the not so obvious. Look for the subtle mechanisms that might be at work. Don't be too hasty to make a judgement. If a wear problem has been persistent despite numerous attempts to solve it, its solution usually lies in the subtle wear mechanism that no one else has been able to detect.
