Frequently Asked Questions

How much do I weld?

Direct Sheet Metal Frequently Asked Questions
When welding in a floor and tunnel, use a rosette weld about 3" to 4" apart. It is not necessary to weld the entire edge of a floor. This will cause severe warpage (too much heat). When welding in a firewall, weld back through the holes you drilled to remove the stock firewall. DO NOT START ON ONE SIDE AND WELD ALL THE WAY TO THE OTHER SIDE.

Is it better to weld the brackets to the frame or bolt them?

Frequently Asked Questions
Be sure that all four corners are tied to the vehicle frame. Each frame bracket must be bolted to the vehicle frame with two bolts, unless optional weld is used. These instructions are guidelines only, actual installation is the responsibility of the installer and the owner. Either way is acceptable. If the you choose to have the brackets welded to the frame, Reese requires the brackets to be welded by a certified welder.

How do I weld stainless steel?

Frequently asked questions
This is not a skill everyone can acquire. Thin stainless can be spot-welded which is suitable for the combustion chamber and case. The NGV assembly will require MIG or TIG welding. TIG sets are expensive and it may be necessary to find a specialist welder used to welding stainless steel to do the welding for you. Modern engines employ a casting for the NGV which is more stable during natural heat cycling.

How thick can it Weld or Cut?

FAQs on the DHC 2000 / Henrob 2000 oxyacetylene torch
It will weld thin metals like automotive sheet metals with minimal warpage up to ½ inch (optional tips may be required) A MIG or stick welder will do thicker 3/16 – ½ materials faster, but if you only have the Henrob it will do it just not as fast as the electric welders.

What is Weld-Crete®?

Larsen Products Corp. Frequently Asked Questions
Weld-Crete®, the original chemical bonding agent for concrete, is a safe, easy to use surface applied bonding agent that bonds new concrete to any clean, structurally sound surface. It has been specified and used by major architects, engineers and construction companies throughout the world since 1952.

How do I weld thick to thin aluminum?

Frequently asked questions about Muggy Weld's Super Alloys
Concentrate the heat on the thick part, as the heat will transfer easily to the thinner aluminum. [back to top]

Can I arc weld?

Neurostimulation for Chronic Pain ? FAQs - Medtronic Neuromo...
It is recommended that the stimulator be turned off and the amplitude set to '0' (if appropriate for the therapy) prior to operating any potentially dangerous equipment. Caution is advised when using arc welders, as they emit large amounts of EMI (see What is EMI/RFI?). It is possible that the magnetic fields generated by arc welding could momentarily induce a voltage into the neurostimulator lead system - and you may feel this as a shock or jolt even when the neurostimulator is turned off.

What is weld decay?

CorrFAQ: Corrosion Frequently Asked Questions
Weld decay refers to the intergranular corrosion, usually of stainless steels or certain nickel-base alloys, that occurs as the result of sensitization in the heat-affected zone during the welding operation.

What is a rosette weld?

Direct Sheet Metal Frequently Asked Questions
A rosette weld is when you punch or drill a hole (approx. 5/16") through one place of material to weld into another piece of material. You use this type of weld when one piece overlaps another piece. All of Direct Sheetmetal’s floors weld in this way.

Do I have to weld anything onto my bike?

FAQs, GPR Stabilizer
NO!!! All our kits are simple bolt-on applications. The small 1% of bikes that require a weld-on are the '95 and older models (if available) and the 85's & 100cc minis with an aftermarket triple clamp. That's the beauty of manufacturing everything in house. It's all in what kind of bike you own that will determine the cost and components necessary to mount up different configurations of dampers, bars, and clamps.

What are some Weld Lock™ features?

Carpet FAQ's
Weld Lock™ features include good strength, locks carpet tufts into place, and dries clear. When wet, it cleans up with water. It is designed for direct stick installations. Apply with a 1/8” continuous bead of Weld Lock™ on one edge.

Are weld plates needed in plank?

Girder-Slab Frequently Asked Questions
It depends upon the diaphragm loads and if they are needed for erection (see Girder-Slab typical details). Consult with your local hollow core supplier for availability of weld plates, alternative details may be suggested that will meet the engineer's requirements. One method is that the hollow core supplier provides these cut outs in the factory and then provides a core plug to stop the grout from flowing too far into the cell.

How does Weld-Crete® work?

Larsen Products Corp. Frequently Asked Questions
Weld-Crete® is applied as a liquid and as it dries to a thin, flexible film, it forms a tenacious bond to the structural surface. The dry film is reactivated by the moisture and chemical reaction that occurs as the new concrete cures. Full bonding strength is achieved after the new concrete has completely cured.

How is Weld-Crete® applied?

Larsen Products Corp. Frequently Asked Questions
Weld-Crete® can be applied by brush, roller, or spray. Do not dilute. When using spray equipment, the nozzle should permit a fog-type spray. Weld-Crete® should be applied in a thin, continuous, film. Do not permit Weld-Crete® to puddle in low areas.

What coverage can be expected for Weld-Crete®?

Larsen Products Corp. Frequently Asked Questions
Yes. Weld-Crete® becomes thicker in colder weather and coverage is reduced. Spraying becomes extremely difficult in cold weather. Do not apply in freezing weather. Do not apply over frozen surfaces.

What surfaces are suitable for Weld-Crete®?

Larsen Products Corp. Frequently Asked Questions
Weld-Crete® may be applied to any clean, structurally sound surface. Weld-Crete® may be applied over painted surfaces provided the paint is clean and well secured to the substrate.

Can you weld CPM steels?

Tech Desk - FAQ
We don't recommend welding our CPM grades, but we know that our customers do it from time to time. We have put together some guidlines for welding in the Tool Steel and Specialty Alloy Selector. You must be aware that the weld area will not have the same properties at the base material. The carbides and grain structure will be courser in the weld area due to the slower solidification rate when welding.

If I want to weld my system together in stainless, what tips do you have?

Stainless Works
We sell mufflers, bends, straight tubing, etc-everything you need to weld a system together. For cutting stainless, a hacksaw or a chop saw with a fiber blade works well. When using a chop saw, make sure to mount the part in the vise very securely-if you pinch the blade with the part the blade will disintegrate. If you cut with a hacksaw go slowly and try to cut as straight as possible. After cutting, sand the pieces so they fit flush using a belt sander and 80 grit or coarser belts.

What is a weld insert ring?

AL-6XN FAQs - Frequently Asked Questions about AL-6XN Alloy
Weld insert rings are used as filler metal for orbital or hand welding AL-6XN alloy. This will "over-alloy" the weld area to compensate for chemical segregation that may take place during the welding process. The filler alloy must have higher molybdenum content than the AL-6XN alloy to compensate for alloy dilution on cooling. Rings are typically available in a 9% molybdenum alloy (Alloy 625), 12% molybdenum alloy (C-22), or 15% molybdenum alloy (C-276).
