Seam sealers such as two components eprov adhesive may be used to stop the seam leaks provided the leakage is not are to rivetting or other defects. In case of seam leaks which are inaccessible for rivetting and wilding, a sealer consisting of fine aluminium powder suspended in two component epoxy or metal binding resin may be used to seal water leaks, 05.4 Sealing Compound : The method of application of sealing compound is as under: The surface should be thoroughly cleaned and dried to remove grease, burrs and other contamination. Apply the sealing compound liberally and pressed using wooden spatula. The sealing compound should then be applied on the tape and again pressed with spatula to ensure proper impregnation into the tape. The second aluminium alloy surface to be joined should then be kept over the tape . Rivettingshould be carried out only after a lapese of 5 to 10 minutes after the solvent has eaporates, Alternatively, The sealing tape should be dipped in the sealing compound and then placed between the surfaces to be rivetted. 214 05.5 Welding: The surface of parts to be welded shall be free from rust, scale, Paint grease and other foreign matter.

Take another sheet, 150 mm150 mmx 1.6 mm thick of A1., alloy 53000 HZ drill 12 non holes 4.5 mm dia with the pitch 9 (Refer sheet “B’ in sketch below) as for the circular sheet. Place sealing tape (dipped in or liberally coated by Geal in compoiund being tested depending upon the method adopted actual fabrication of boat) between the two sheets “A’ and ‘B’ and riveta and rivetting dolly (refer sketch below).Ensure proper formating of rivet heads. Three such test pieces should be prepared. ii.Allow the three test pieces prepared as above to age at room temperature for 72 hrs. After 72 hrs of ageing, one test piecdshould be tested by subjecting it to 100 cma of water column head inwaterproofness test apparatus (for low pra=essure for 76 mm diameter disk desoribed inBS:903 Part G-5) for a austained period of one hour. If there is no leakage of water aither from the seems or around the rivet heads, the test piece is sonsidered to have passed this test. If this test piece fails, the remaining two test apecirans should be passed this test if both these apecimens are found to be satisfactory as per the above test procedure. (b) Compatibility for applicationon A1 Alloy. Sealing compound under testing is applied directly on three pieces of A1 alloy 53000 HZ sheet. These are eranised resally after 72nhrs of againg at room temperature. If there is no sign of adverae oheanieal reacties between the sealing compound and any f the A1 Alloy sheets, the sample sealing compound is considered to here passed this test. (c) Ageing Test. Repeat tests (a) and (b) above after 20 days 9 from the date of fabrication of test pieces) or againg at room temperature. If the sample passes these tests, it is considered to have passed this test also. 2. If the sample of sealing compound passes tests mentioned in paras 1(a), (b) and (c) above, the same is considered as acceptable. 221 SPECIFICATION FOR OUTBOARD MOTOR 50 HP NO.
