cookoff winners
Congratulations to Joe Rios, Carlos Hernandez and the rest of the Smokin’ Welders team who cleaned up big at a cookoff hosted by the Associated Builders and Contractors Texas Gulf Coast chapter.

We entered 3 teams in this year’s cookoff which collectively won the title of Grand Champion. The individual Red-D-Arc teams  dominated the contest with the following results in the various  categories:

Fajitas – 2nd, 3rd and 4th place
Chicken – 4th, 5th and 7th place
Brisket – 1st, 4th and 10th place
Ribs – 1st, 4th and 7th place

The annual cook-off was held to raise money for Veterans and The Back-Packs for kids program which sends food home with school kids that need food for the weekends. The contest also helps support the Dream Center which provides kids in need with shoes, clothes and school supplies.

We tried to get Carlos to share some of his recipes, but he was hesitant about giving up his winning secrets.

Great job guys. Thanks to everyone who helped the RDA Smokin’ Welders win big.

Dry Ice Blasting Paint Booth Rental Package

Paint Booth Blast Cleaning
Industrial paint booths require periodic cleaning in order to maintain productivity and quality. On average, paint booth cleaning intervals range between 6 to 12 months. Typical cleaning methods involve hand scraping and wire brushing. Awkward angles and hard-to-clean areas like seams and bolt heads make this time consuming process very challenging.

To help our customers address this challenge Red-D-Arc has developed a Dry Ice Blasting Paint Booth Rental Package. This turnkey solution includes dry ice blasting machines, dry ice, high pressure air (if required), synthetic coatings (to limit future paint adhesion on booth interior) and on-site operating and safety training.

With the support of Red-D-Arc Blast Cleaning Specialists, plant maintenance teams are able to leverage dry ice blasting technology themselves rather than using specialized service contractors, which amounts to significant savings.

Strengthening Metal Parts with Hardfacing

Metallic parts sometimes fail their intended use at a lower stress than they are designated for.
Various forms of wear such as abrasion, impact, metal to metal contact, heat, and corrosion can compromise the strength of metal pieces. This is where hardfacing comes in. Hardfacing is a technique which can be applied to minimize the damage from these types of wear, helping to prolong the life of metal pieces.

What is hardfacing?

Hardfacing —often called hardsurfacing— is the covering of the metallic part with a wear resistant metal by welding. Alloys which commonly need to be hardfaced include carbon alloy and low alloy steels whose carbon content is lower than 1 %. These include stainless steels, manganese steels, cast iron as well as nickel and copper-based alloys.

Metallic parts sometimes fail their intended use at a lower stress than they are designated for.

Techniques, Materials and Costs

The particular hardfacing technique for a job depends on the geometry of the part and relative cost of the hardfacing method. Costs can vary with the deposition rate of the material.

These cost variations can be summarized as follows:

  • Flux cored arc welding (FCAW) 8 to 25 lb/hr
  • Shielded Metal Arc Welding (SMAW) 3 to 5 lb/hr
  • Gas Metal Arc Welding (GMAW), including both gas-shielded and open arc welding 5 to 12 lb/hr
  • Oxyfuel Welding (OFW) 5 to 10 lb/hr

 

Applied materials commonly include cobalt based alloys such as STELITE, and nickel based materials like chromium carbide alloys. More advanced materials such as complex carbides containing columbium, molybdenum, tungsten, or vanadium can also be used and provide more overall abrasion resistance. They also have a very low friction factor, which can be used in situations involving severe abrasion.

Hardfacing can be applied to both newly manufactured pieces, in order to prevent deterioration, or to strengthen and extend the life of worn pieces currently in use.

Red-D-Arc provides welding machines suitable for hardfacing using techniques including SMAW, FCAW and GMAW.

Is Gas Welding Really Cheaper?

Oxy acetylene welding torch

The answer is often no, and here’s why…

Gas (oxy-acetylene) welders used to be the rock stars of welding. From shipbuilding to automotive manufacturing to steel forging, but that was then. Arc welding is a modern welding method that outmatches gas welding in almost every respect.

Weld finishing:

Arc welders use electric current generated by a transformer or a generator to produce a uniform, clean welds that almost never require finishing. This is not the case with gas welding. Gas welding operates using the heat generated by the ignition of a gas mixture (oxygen and acetylene) to melt the welding material or to simply fuse two parts together. This process often results in a bad surface finish. Gas welding can require additional work involving hours of grinding and polishing the welds.
