Here are some more information for Stainless Welding:
Cost to replace=$29.95 plus + $5.05 FOR S&H TOTAL $35.
Cost to repair using a mini-weld model 6 Airless plastic welder. 3 welding rods .12 CENTS EACH, stainless steel mesh .15 CENTS, 3 inches of fiber flex welding rod .13 CENTS TOTAL COST OF REPAIR=.64 CENTS.
WITH A PLASTIC WELDER, I WAS ABLE TO SAVE $34.36.
1) Work area
o Make sure work area is clean and well ventilated.
o Identify plastic- You need to know what kind of plastic it is. So that you can use the right plastic welding rod. In most cases there will be a mark on the part that will tell you what kind of plastic it is, but in this cases there was no mark on part. We will work on this in step 3.
o Turn plastic welder to preheat before going to step 2. This will allow the plastic welder to heat up how you're cleaning and setting up the plastic planter.
2) Parts to be welded
o Clean parts with soap and water.
o Let dry or towel dry
o Set parts up for welding. If there are broken pieces try to put back together using tape to hold them until ready to weld. Try to make sure that the cracks are flat and even before welding.
3) Set the plastic welder to the correct heat setting for the plastic being welded.
o Since we don't know what kind of plastic we are working with. We will have to try different welding rods to see which one will hold the best. PP and Fiber-Flex plastic welding rods held the best.
o So these are the rods I used for this repair.
4) Weld the plastic together.
o Using the edge of the welder go along the crack and make a groove.
o Use the PP welding rod fill in the groove. Let the heat do all the work don't force it. Just melt the filler rod into the groove.
o If you think that you'll need added strength at the weld you can use stainless steel mesh. Just heat the mesh up and the plastic will form around the mesh where you can't see it.
o Don't try to weld the whole piece at once. Just work on about a 1 inch to 2 inch at a time.
o If plastic gets to hot and starts to deform cool it off with water and start welding again.
5) When finished welding
o Turn the welder off and let cool.
o Let the welded part cool. You can use a rag with water to help cool it off faster.
o When part is cool. You can start to finish the weld. I use 60 grit sand paper then go to 180 grit sand paper to make the plastic smooth.
o Now because the plastic does not match this is your option.
A) The part can be painted any color you want. Just get paint for plastic.
B) You will not be able to see the part that is black because you will be adding dirt to the box and this will cover it.
6) Let the paint dry and start using your grow box!

Commonly Used Stainless Steel Grades
Stainless Steel grades are essentially alloys of iron with more than 10.5% chromium. These grades may contain additional elements of nickel, manganese, carbon, nitrogen and silicon. They can further be modified for special purposes by addition of molybdenum, titanium, niobium, silicon, sulphur etc. A wide range of these grades have been developed based on specific requirements. These are classified into following categories based on their micro structure:
Ferritic Stainless Steel
Ferritic Stainless Steel grades are non-hardenable plain chromium grades with chromium content varying from 10.5% to 28% and with low carbon content. These are magnetic and exhibit a better resistance to corrosion than martensitic grades. These grades are employed in applications where the desired formability, weldability and corrosion resistance is between those of martensitic and austenitic types. The ferritics can be polished or buffed to achieve high lustre.
Martensitic Stainless Steel
Martensitic Stainless Steel grades are plain chromium grades containing 11.5 % to 18% of chromium with relatively high carbon content (0.1% – 1.2%). Initially developed for cutlery, these are well suited for applications requiring high hardness and resistance to abrasion and erosion. These grades are magnetic and display fair cold forming characteristics. Although these can be hardened by air-cooling, oil quenching is sometimes used to assure uniform hardening. These grades can beDuplex Stainless Steel welded but require stress relieving after welding. They exhibit their best corrosion resistance in the hardened condition and perform well in mildly corrosive environments. Martensitic Stainless Steel grades are commonly used for knife blades, turbine blades, surgical instruments, fasteners, shafts, spindles, valves and pins.
Austenitic Stainless Steel
Austenitic Stainless Steel grades are characterized by superior corrosion and oxidation resistance, weldability, ductility and toughness compared to ferritic and martensitic Stainless Steel grades for similar levels of chromium.
Austenitic Stainless Steel grades exhibit excellent resistance to atmospheric corrosion. They effectively withstand attack of organic acids (e.g. acetic, lactic, citric etc.), exhibit good resistance to oxidizing acids (e.g. nitric acid) and fair resistance to mineral acids (e.g. sulfuric acid). These grades are well suited for severe forming. Some grades work harden to a high degree while others have been developed to minimize this tendency. Work hardening is advantageous in certain cases where high strength is required. Austenitic Stainless Steel grades are non-magnetic in annealed condition but depending on composition, they may become mildly magnetic when cold worked. These Stainless Steel grades possess good high temperature properties such as creep strength and resistance to oxidation or scaling. They also exhibit excellent low temperature ductility and impact strength. Austenitic Stainless Steel grades can be readily fabricated by bending, drawing, spinning, punching, drilling, machining and welding and can be readily polished to a high finish. These attributes make them very versatile and popular for diverse applications in a variety of industries.
There are two broad categories of Austenitic Stainless Steel — chrome-nickel (300 series) and chrome-manganese (200 Series).
Currently, chrome-nickel is the largest produced Stainless Steel category globally. Typical applications for this category include food processing, chemical plants, pharmaceutical equipment, hospitals, textile, architectural, building construction, kitchenware, consumer durables etc.
Chrome-manganese Stainless Steel is the fastest growing of all Stainless Steel categories on account of its high performance to cost ratio. Its applications include kitchenware, cutlery, sinks, automotive trim, architectural, buildings, furniture, buses, trains and ornamental tubes.
Duplex Stainless Steel
Duplex Stainless Steel grades contain relatively high chromium (between 18% and 28%) and moderate amounts of nickel (1% to 8%). This combination of ferritic and austenitic structures is called duplex. Many of these grades contain molybdenum (1% to 5%) and nitrogen (0.05% to 0.3%). Some duplex Stainless Steel grades also contain manganese (up to 5%), copper (up to 2%) and tungsten (up to 2%). These grades exhibit high resistance to stress corrosion cracking and chloride ion attack and have higher yield strength than that of austenitic or ferritic steel grades. These properties combined with suitable design lead to material saving. High quality fabrication and welding are possible if the operator is trained well. These grades are used in marine applications, offshore platforms, paper and pulp industry, chemical, petrochemical and desalination plants.

welding stainless steel?
i have a lincoln 175 running 10 l/min 100% argon with .035 stainless wire.setting A-2.5 my welds are really tall and bulky also there is a constant pop when i try and weld stainless new to this can someone please help am i holding gun to far off or what.
If the welds are tall and bulky, the temp is too low and you are "cold welding". OR, you are moving too slow. You are not fusing the metal. Make sure the surface is clean.
