FastROOT to success
Further development of FastMig Synergic welding systems with FastROOT process for effective root pass welding.
W
elding systems specialist Kemppi continues to add power sources, processes and feeding system
capability to its industrial 3-phase FastMig Synergic MIG/MAG welding systems, which are offered with either the SF 52 or SF 53 function control panel and optional FastROOT process soſtware. Designed for accurate weld root pass
welding with mild and stainless steels used in industrial pipe and tube installations as well as heavy to medium fabrication work, including shipyards, offshore work and structural steel applications, FastMig Synergic provides the welder with a choice of energy saving KMS 300, 400 and 500 power sources. Te system has power to weight ratios and MSF53, 55 and 57 wire feed units for 200mm or 300mm wire spools, plus the option of either the SF52 or 53 control panel for root pass welding, with all the basic functions plus crater filling, hot and creep start and memory for storing welding parameters. All the wire feed units have 4 x 32mm
short-arc welding process, where the power source’s current and voltage parameters are digitally controlled for accurate and fast MIG/MAG root pass and thin sheet welding on mild steel and stainless steels. Tis enables plate and pipe welders to weld in all positions using the same equipment for root pass welding with good root surfaces and root side shape with minimal requirements for post weld finishing or capping. Tis soſtware can be retrofitted into existing

diameter feed rolls, a 0-25m/min wire feed speed for solid and cored wires as well as aluminium with diameters ranging from 0.6mm-2.4mm. Kemppi’s FastCool 10 water cooling unit is also available as an option. To date, key developments in the system
by the finnish company have included the modification of FastROOT software, the
FastMig Synergic machines having either the SF52 or SF53 control panels. It is installed using a special activation code through either control panel. It also comes supplied with a DVD providing both installation instructions and information about root pass welding techniques. Mike Pixley, Kemppi (UK) Ltd managing
director, said that further development of the system was in train. Kemppi is process testing a new feeding system at two UK yards, the so-called ‘Supersnake’, which is designed to be fed through bulkhead apertures. NA
Heavy metal-free SeaGuard
Sherwin-Williams Protective & Marine Coatings Division introduces SeaGuard heavy metal free antifoulant.
which is presented as an environmentally responsible alternative to copper-based hull coatings that prevents the growth of marine organisms on commercial and military ships. The new product, which has US EPA
S
approval, is a solvent-based ablative coating that utilises a metal-free organic biocide agent, but nonetheless is said to provide equivalent antifouling protection capability as traditional copper-based coatings. “Because the antifouling agent in SeaGuard Heavy Metal Free has an extremely short hydrolytic half-life, it does not persist or accumulate in the marine environment and will not harm

marine organisms,” the company says. “Te breakdown products are biodegradable.” Traditional antifoulings utilise metals such
as copper as active antifouling agents. Tese metals can harm marine life as, over time, they leach from ship hulls and concentrate in sediment. Te issue is of particular concern in estuaries and bays that flush slowly, such as San Diego Bay. SeaGuard is also said to offer shipowners
fuel savings compared to traditional antifoulings because it eliminating reduction in weight of 40% compared to traditional copper antifoulings. “Tis is a first in our product offering to the
US military and US commercial ship owners - an environmentally responsible alternative to
metal-based antifoulings that not only meets performance expectations but can actually increase fuel efficiency”, said Doni Riddle, vice president, Sherwin-Williams Protective & Marine Coatings Division. Another environmental advantage of
SeaGuard Heavy Metal Free Antifoulant is its lower level of Volatile Organic Compounds (VOCs) – less than 340 g/L. It may be applied at temperatures as low as 10o
C. Available in red or black, SeaGuard is an
ablative coating, which allows the coating surface to slough off gradually, exposing new biocide that maintains the coating’s effectiveness over time. It can be used to overcoat existing antifouling coating systems. NA
