AWS A2.4.
A - is electrode chemical analysis number.
AWS 5.1/E-XXXX
Rigging process depends on three factors
☛ Capacity of the hoisting device
☛ Working loads of ropes and hardware
☛ Weight of the load to be lifted
Blueprint reading is like a structural map that covers the steel structure. It is a detail drawing of steel structure, and it carries a label or piece mark to differentiate one steel bar or structure from others. Each piece or segment of steel structure has a single blueprint with detailed information before it become the part of the whole. It carries information even small as hole sizes, dimension, etc.
☛ Build steel and or iron girders, columns and other construction based structures
☛ Make, weld and bolt down steel bars to reinforce concrete
☛ Connect steel columns, beams, and girders
☛ Reinforce concrete with welded wire fabrics
☛ Position steel or iron structures with connecting bars and spud wrenches
☛ Check the alignment using plumb bobs, levels, and laser equipment
☛ Fasten bars together with wire
☛ Drill holes into steel for bolts
☛ According to assembly instructions number the steel structures
☛ Hoist steel into the framework
☛ Inspecting material and equipment’s
we can use at root pass for deep penetration
Max 3 times of electrode diameter.
120 to 250 degree temperature.
PQR stands for procedure qualification record. The PQR documents what occurred during welding the test coupon and the results of testing of the coupon.
Test pressure plus10% (10% should be lesser than 50Psi).
ASME B31.4
I use a 25% scale when I am working on task that gives me the opportunity to keep track of my time an how each task is going also using hard dates to keep with my self not to go over.
Welding robots have their own set of maintenance needs. Robotic welding systems have to keep everything regulated correctly – torch angle, wire feed, gas flow. As with most equipment, when it comes to welding robots, a little maintenance goes a long way. RobotWorx recommends paying attention to these items for the best results:
* Proper connection of welding leads: Positive from power source to wire feeder and negative from power source to work piece, table, and fixture.
* Wire feeder: The wire drive roll needs to have the proper tension and the rollers must be the proper size.
* Welding Gun: Check the condition of torch contact tips, nozzles, and make sure there is the right amount of gas flowing through the gun.
* Robot Tool Center Point (TCP): Make sure you’ve programmed this point correctly. It controls the torch’s position and makes it possible for the robot to perform the proper movements.
Explain it as best as possible and listen to his or her ideas and try to collaborate maybe on of their ideas improve on mine of vise versa.
Yes, manufacturing keeps me on my toes and have to be ready for deadlines as well as line stoppages. So keeping up with my time and using it wisely is very important.
The Robotic Industries Association (RIA) standard is the ANSI/RIA R15.06-1999, Safety Requirements for Industrial Robots and Robot Systems.
The ANSI/RIA is not a law but a voluntary American National Standard. Adhering to it is not so much a legal issue as it is a compliance issue. As more and more users require compliance with the standard in their contract specifications, you may be obligated to comply with the standard. More contracts will be let this way, since the user is required to comply with OSHA directives that include voluntary standards by reference.
Symptoms of lead poisoning includes
☛ Loss of appetite
☛ Nausea
☛ Vomiting
☛ Stomach cramps
☛ Constipation
☛ Insomnia
ROI stands for “Return on Investment”. This is the amount your company will save by incorporating robots. A robotic system typically produces the same output as 4 welders. The annual savings (ROI) can be calculated as follows:
ROI = [(x + y) * 4 – z] * t
x = Hourly Rate of Welder
y = Equipment Cost Per Hour
z = Robotic System Cost Per Hour
t = 2080 Hours Per Year
