Here are some more information for Welding Fabricating:
Glass Fiber Reinforced Polymer is a substance composed of a plastic matrix that is embedded with glass fibers to provide strength and reinforcement. Fiber reinforced polymer is used to build architectural elements, car parts, bridges, and consumer products. This article will outline the methods used to fabricate GFRP and the physical properties of fiber reinforced polymer that can help determine its quality.
GFRP Fabrication: How It's Made
Although all types of Glass Fiber Reinforced Plastic are composed of a plastic matrix and glass fibers, there are actually several fiber reinforced polymer manufacturing methods that are commonly used.
The first method of manufacturing Glass Fiber Reinforced Polymer is what is known as the hand lay-up method. Although very precise, this method is also quite labor intensive. In the hand lay-up method, a resin that has been combined with a catalyst is placed inside of a mold. Fiberglass is then packed into the mold with steel rollers. This process may be repeated one or more times. The resin will usually start to cure quite quickly, depending on the exact amount of catalyst used, so the task must be completed relatively fast when this method of GFRP fabrication is used.
Another common method of GFRP fabrication is the spray lay-up process. It is similar to the former method in many respects. The main difference is how the resin and glass fibers are placed into the mold. Instead of being placed into molds by hand, these substances are sprayed in. Not surprisingly, this method of fabricating fiber reinforced polymer is faster than the previous.
One other GFRP fabrication process that may be used is what is known as resin transfer molding. In this method, glass fibers only are added to a mold. The mold is closed, and the resin matrix is injected under pressure. Once the resin cures, the product is removed from the mold.
Properties of GFRP
The quality and strength of architectural fiberglass and other types of GFRP can vary widely depending on the quality of the resin used, the fabrication method employed, and the level of expertise of the individual who made the GFRP. The quality of all types of fiberglass reinforced polymer can be determined by evaluating a number of the material's properties, including:
- Compressive strength: How much stress can be placed on the FRP before it is crushed?
- Tensile strength: How much can the FRP be stretched before it breaks?
- Flexural strength: How far can the Glass Fiber Reinforced Polymer bend before breaking?
- Impact strength: How big of a force, either on its edge or its front surface, can the GFRP withstand before breaking?
Ideally, GFRP will rate well in each of the above categories. Before buying GFRP products, it is always a wise idea to ask about the company's level of experience working with fiber reinforced polymer and their past projects to help ensure the GFRP products being sold are of the highest quality.

Robotic Welding Comes Of Age
Robotic welding has come of age in the past few years. In advances in computer technology and robotics, simple, repetitive tasks in manufacturing are often performed by robotic welding devices, with a resulting savings in labor and an improvement in safety, since there is less human interaction and less chance for human error.
Trade shows and conventions for the fabrication industry and welding trades often feature robotic welding devices these days. Demonstrations at the trade shows give examples of robotic welding machines doing graceful and complex maneuvers, demonstrating speed and flexibility possible with robots today that were not possible a generation ago.
Industrial robots are used in welding, painting, ironing, assembly, palletizing, pick and place, inspection, and testing of products. Robots have proven themselves to be valuable resources in manufacturing applications in all of these areas.
Any welding task is suitable for automation if the task is repetitive. From a practical, financial standpoint however the number of pieces that need to be welded must be of sufficient quantity to allow a continuous flow, to justify the initial expense of setting up robotic welding machinery. In such instances an automatic welding gun can be placed in a static position or if needed on a curved track to achieve a circular weld. In this type of situation, a work piece can be rotated past the welding gun.
The major manufacturers in three basic sizes offer robotic welding arms. These include a tabletop size with a six-pound payload, a medium sized model with a 13.2 pound payload and larger machines with a 22.2 pound payload. While these robotic welding machines are available new, many used and reconditioned models are also available and popular.
Where robotic welding machines, and industrial robots in general came from is of interest. The first industrial robot, used for simple tasks, was invented in 1962. In 1969 a Stanford University professor developed the Stanford arm, an articulated robot that widened the potential of robots, making robotic welding possible and feasible. By the 1970's industrial robots were firmly rooted in most industries and robotic welding's strong points had become obvious to industry. Soon large companies like General Electric and General Motors were manufacturing robots, and several companies n the U.S. stated specifically to manufacture them and market them to industry, including Automatix and Adept Technology, Inc, while Westinghouse Electric Corporation acquired Animation, the grandmaster of industrial robotics. Many Japanese companies also entered the arena.
Today's popularity of industrial robots, and in particular of robotic welding devices is due to the fact that these machines save man hours, allowing skilled human technicians, including welders, to concentrate on more complicated tasks worthy of their skills and training. Simple and repetitive tasks that would be a waste of a skilled welder's time are generally handled by robotic welding machines with cost savings in the millions every year, benefiting the companies and stockholders.
Overall, Robotic welding is one of the most advanced computer technologies and robotic welding devices save in labor and an improvement in safety, by reducing human error and human tragedy.

Fabricated steel sculpture?
Hi all, I need some ideas for a project in fabricated steel sculpture that involves welding steel and making a sculpture by using mix media.
I would suggest welding some steel, and then mixing up some media and combining it. If this is for an art class you probably ought to develop some kind of personal connection to your work.
